lookups.
This uses a special variable name based on a hash of ${CC}, ${PATH}, and
${MACHINE} to ensure that a cached value is not used if any of these
values changes to use a new compiler.
Before this there were 34,620 fork/exec from bsd.compiler.mk during a buildworld.
After this there are 608. More improvement is needed to cache a value from
the top-level before descending into subdirs in the various build phases.

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+.

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.

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 '+'.

Before this, if a file was installed to DESTDIR/some/dir and that directory
was missing due to not having ran 'make distrib-dirs' yet, the file would
be installed as 'some/dir'. For something like bsd.incs.mk with INCLUDEDIR
being a sub-directory of /usr/include, this could result in all of the headers
being installed to a file rather than getting a directory of them.
Now it will error that the file/directory does not exist rather than hide
the issue.
Another option being discussed is to implement GNU's install -D flag which
would auto create any missing directories.
This is a mitigation of the problem. The proper order to the build is to
run 'make distrib-dirs' first, but that can be forgotten if building from
a sub-directory after updating the source code to the latest revision.

The 'config' target isn't really needed right now so just remove it to avoid
any clashes with config(8) building. It's also likely misspelled and should
be 'configs' if we decide to add it back. This was just a convenience
target recently added.

On each resolver query, use stat(2) to see if the modification time
of /etc/resolv.conf has changed. If so, reload the file and reinitialize
the resolver library. However, only call stat(2) if at least two seconds
have passed since the last call to stat(2), since calling it on every
query could kill performance.
This new behavior is enabled by default. Add a "reload-period" option
to disable it or change the period of the test.
Document this behavior and option in resolv.conf(5).
Polish the man page just enough to appease igor.

For example in lib/atf/libatf-c++/tests/detail it is now possible to
run 'make application_test'. This was intended to worked for PROGS,
but lacked support for PROGS_CXX.
Also fix redefining the main PROG target to recurse. This isn't needed
since the main process is setting PROG/PROG_CXX to handle it directly
via bsd.prog.mk.

more typical ALL_SUBDIR_TARGETS entries and target hooks in bsd.incs.mk,
bsd.files.mk and bsd.confs.mk.
This allows the targets to be NOPs if unneeded and still work with the
shortcut 'make includes' to build and then install in a parallel-safe manner.
Sort and re-indent the ALL_SUBDIR_TARGETS with the new entries.

The SUBDIR_TARGETS variable should really be named LOCAL_SUBDIR_TARGETS, but
renaming it may be a surprise for downstream vendors who use this variable.

Before this, the target was unknown. Now it will recurse on subdirs and run
the target in the current directory. It is required to recurse as there
may be subdirs that have objs in their directory or in the object directory,
so it is not enough to just delete the objdir of the subdir parent.

- projects/bmake and subsequent commits provide SRCTOP; there's no need to
manually specify it now.
- Compute a sane default for OBJTOP based on .OBJDIR and RELDIR. Manually
specifying this is probably no longer needed, but it persists just in case
(supporting commits will need to be made to move it out of some of the meta
.mk files).
- Compute a sane default for TESTSRC. Error out if the path cannot be found.
