when -fstack-protector-strong is not available, like it was implicitly before
r288669
As noted by antoine@, devel/gcc (which is 4.8.5) lacks -fstack-protector-strong
support, whereas 4.8.4i (devel/gcc48) has the support.
Until a version is available which has -fstack-protector-strong support, be
conservative and only enable support with 4.9+.

value is defined as a config option the definition is emitted into
opt_global.h which is force-included into everything. In addition, the
symbol is emitted by the genassym mechanism, but that by its nature reduces
the value to a 0xnnnnnnnn number. When compiling a .S file you end up
with two different definitions of the macro (they evaluate to the same
number, but the text is different, upsetting the compiler).
Nothing has changed about this code for a while but the compile error is
new, so this must be fallout from the clang 3.7 update or something.
The early ethernet MACs (I think AR71xx and AR913x) require that both
TX and RX require 4-byte alignment for all packets.
The later MACs have started relaxing the requirements.
For now, the 1-byte TX and 1-byte RX alignment requirements are only for
the QCA955x SoCs. I'll add in the relaxed requirements as I review the
datasheets and do testing.
* Add a hardware flags field and 1-byte / 4-byte TX/RX alignment.
* .. defaulting to 4-byte TX and 4-byte RX alignment.
* Only enforce the TX alignment fixup if the hardware requires a 4-byte
TX alignment. This avoids a call to m_defrag().
* Add counters for various situations for further debugging.
* Set the 1-byte and 4-byte busdma alignment requirement when
the tag is created.
This improves the straight bridging performance from 130mbit/sec
to 180mbit/sec, purely by removing the need for TX path bounce buffers.
The main performance issue is the RX alignment requirement and any RX
bounce buffering that's occuring. (In a local test, removing the RX
fixup path and just aligning buffers raises the performance to above
400mbit/sec.
In theory it's a no-op for SoCs before the QCA955x.
Tested:
* QCA9558 SoC in AP135 board, using software bridging between arge0/arge1.
an extra argument to specify the number of 1GiB pages to map. This should
be a nop as we are only mapping a single page, but when we move to use an
extra level of page tables we will be able to map a second block, e.g. if
the kernel was loaded over a 1GiB boundary.
This includes clang 3.5.0+, gcc 4.2.1, gcc 4.8.4+
This allows me to do subdirectory makes again after setting
MAKESYSPATH on 10.2-RELEASE as it comes with clang 3.4.1.
As a sidenote: this isn't technically correct for all vintages
of gcc 4.2.1, but will be correct when gcc is rebuilt/reinstalled
after r286074, so this version check should be good enough.

The 'includes' target is currently a pseudo target in bsd.subdir.mk that
does 'cd ${.CURDIR} && ${MAKE} buildincludes && ${MAKE} installincludes',
versus all over targets that just recurse.
In Makefile.inc1 the older duplicated bsd.subdir.mk logic for calling
'includes' was being executed in each subdir directly, meaning 'cd lib && make
includes' became 'cd lib && make buildincludes && make installincludes'. Now
that the bsd.subdir.mk logic is used it is calling 'make buildincludes && make
installincludes' from the top-level which pulls in the PATH=<default path>
from /Makefile.
The sub-make logic for 'includes' in bsd.subdir.mk was attempted to be removed
in r289282 but turned out to be wrong. I have a working version now but
it is not yet ready for commit. So for now in Makefile.inc1 split out
'includes' to 'buildincludes' and 'installincludes' which will avoid the
problem.

Bmake has a documented feature of '-N' to skip executing commands which is
specifically intended for debugging top-level builds and not recursing into
sub-directories. This matches the older 'make -n' behavior we added which made
'-n -n' the recursing target and '-n' a non-recursing target.
Removing the '-n -n' feature allows the build to work as documented in
the bmake manpage with '-n' and '-N'. The older '-n -n' feature was also
not documented anywhere that I could see.
Note that the ${_+_} var is still needed as currently bmake incorrectly
executes '+' commands when '-N' is specified.
The '-n' and '-n -n' features were broken for several reasons prior to this.
r251748 made '_+_' never expand with '-n -n' which resulted in many
sub-directories not being visited until fixed 2 years later in r288391, and
many targets were given .MAKE over the past few years which resulted in
non-sub-make commands, such as rm and ln and mtree, to be executed.
This should also allow removing some indirection hacks in bsd.subdir.mk and
other cases of .USE that have a .MAKE by using '+'.

Back in r30113, the 'par-*' targets were added to parallelize portions of
the build in a very similar fashion as the SUBDIR_PARALLEL feature used in
r263778. Calling a target without 'par-' (for 'parallel') resulted in the
standard bsd.subdir.mk handling without parallelization. Given we have
SUBDIR_PARALLEL now there is no reason to duplicate the handling here.
In build logs this will result in the ${dir}.${target}__D targets now showing
as the normal ${target}_subdir_${dir} targets.
I audited all of the uses of Makefile.inc1 and Makefile's targets that use
bsd.subdir.mk and found that all but 'all' and 'install' were fine to use
as always parallel.
- For 'install' (from installworld -j) the ordering of lib/ and libexec/
before the rest of the system (described in r289433), and etc/ being last
(described in r289435), is all that matters. So now a .WAIT is added in
the proper places when invoking any 'install*' target. A parallel
installworld does work and took 46% of the time a non-parallel
install would take on my system with -j15 to ZFS.
- For 'all' I left the default handling for this to not run in parallel. A
'par-all' target is still used by the 'everything' stage of buildworld
to continue building in parallel as it already has been. This works
because most of the dependencies are handled by the early bootstrap
phases as well as 'libraries' and 'includes' phases. This lets
all of the SUBDIR build in parallel fine, such as bin/ and lib/. This
will not work if the user invokes 'all' though as we have dependencies
spread all over the system with no way to depend between them (except
for the dirdeps feature in the META_MODE build). Calling 'make all'
from the top-level is still useful at least when using SUBDIR_OVERRIDE.

The ordering of 'etc' in the install has a long history dating back to the
first time it was realized it needed to be "last" in r4486. That commit
still left it before LOCAL_DIRS though. By having it before LOCAL_DIRS
any manpages they install were not being added to the whatis database in the
install image. They would likely show up in the file after a periodic
rebuild of the file though.
Currently the whatis file is built by an 'afterinstall' hook in etc/Makefile
that calls share/man's 'makedb' target.

There are still issues with mid-install errors leaving a system unusable that
are currently non-trivial to solve. The safest ordering requires installing
rtld, libc and libthr (in that order) before anything else. We don't do that
now though. Much improvement is needed here still.
