bc5c3aad41 Unbreak the build for some modules that depend on -std flags to be passed
through via CFLAGS, as noted by Jenkins when building sparc64 by re-adding
bsd.sys.mk to bsd.kmod.mk:
https://jenkins.freebsd.org/job/FreeBSD_HEAD_sparc64/225/changes

Tested with:
    % cd /sys/modules/bce; make obj; make depend; make all

7ed11c5e5a Fix module builds on arm (and maybe others) by turning off a whole
raft of new warnings that appear to be on by default in clang 3.5.0.
Fix RPI-B build issues with new clang not liking the ability to pass
arbitrary flags to as, since some flags are more arbitrary (and thus
verboten) than others.

These warnings should be actually fixed in the code, but this is a
band-aide to get things (almost) building again.

e1e6143854 Check if ${_dir}/kern exists as well, because if it doesn't exists
we will fail later and we can miss good kernel source tree directory.
I found this trying to compile kld module and it finds 'conf/kmod.mk'
in '../..', but it fails later, because there is no 'kern' directory,
but there is valid kernel source tree still in /usr/src/sys/.

d510ecb42b Bring in the WARNS directive from NetBSD, localized in a new bsd.sys.mk
to avoid polluting sys.mk.  This directive controls the addition of
compiler warning flags to CFLAGS in a relatively compiler-neutral manner.

The idea is that WARNS can be set in Makefile.inc or in individual
Makefiles as they become clean, to prevent the introduction of new
warnings in the code.  -Werror is added by default

aabafca098 Do not check for existence of ${_dir}/kern/ , because for modules that set
.PATH to ${.CURDIR}/[...]/kern , the "exists" expression will fail for the
form exists(${.CURDIR}/[...]/kern/).  This appears to be happening because
make is searching for the argument to "exists" by using .PATH rather than a
relative search, because .PATH and the argument match at the beginning.
Additionally, make appears to consider a path that starts with ${.CURDIR}
as relative, even though it expands to an absolute path.

The reason that most people aren't seeing this problem is that the absolute
paths of /usr/src/sys and /sys are also searched, so as long as the kernel
source can be found in at least one of those places, no problems surface.
This problem was inadvertently introduced on 1 December 2000, with the
addition of the sysvipc modules.

c7c5a4ed23 Add ${.CURDIR}/../../../.. to the list of places we look for the

09be11ba99 Remove KMODDEPS support. All our existing dependencies are specified
via the MODULE_VERSION() and MODULE_DEPEND() macros that both the loader
and kld system know how to deal with.  The old DT_NEEDED tag is still
supported by the loader (and will remain supported for a while) - but the
kernel side presently doesn't know how to deal with DT_NEEDED.

9a8631b340 Add support for compiling kernel modules outside of the tree. If you
do not have the kernel you wish to compile against in either
/usr/src/sys or /sys, then you will need to set SYSDIR to point to the
sys directory of the source tree that contians the source.

Also, minor tweaks to the load/unload targets from Bruce.

I've had this through several make worlds, as well as using it on a
daily basis for the past couple of weeks to build modules needed for
testing at Timing Solutions.

9e0f2a9fb1 Use an intermediate file containing the module binary before converting
it into a ``shared'' .ko file.  This intermediate file can be directly
linked into a static kernel.  This isn't all that useful yet but will
become much more interesting shortly.

a0b845fe92 Add "-I@/../include" and/or "-I${DESTDIR}/usr/include" to CFLAGS,
essentially as in kernel makefiles, so that module sources can include
<stddef.h> and other standard headers.  Only add the second path when
the first path can't be found, instead of when DESTDIR is defined.
Adding it used to be just an obfuscation.

Use "${.OBJDIR}" instyead of "." in -I paths.  Using "${.OBJDIR}" just
gave more verbose command lines and depend files.

c447342094 Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot).  This is consistant with the other
BSD's who made this change quite some time ago.  More commits to come.

3b073b53b7 Update vnode_if.sh location. This was deliberately left a while after
the repo copy as the kernel src/sys/modules stuff uses
/usr/share/mk/bsd.kmod.mk which often gets out of sync with the kernel
source.

9029b6442a Use the -c and -h args of vnode_if.sh to generate only the .h file that
we use.  The .c half is statically compiled into the kernel.  It's kinda
silly to generate a .h file on the fly that has inlines to call the
.c stuff when the .c code is fixed.

Also, zap the special treatment for VFS_KLD modules.  This treatment
applies to lots of things, not just VFS's.

4fea670478 Build and clean device interface files (foo_if.[ch]) and empty options
files (opt_*.h) automatically (if they are in ${SRCS}).

Clean vnode_if.[ch] automatically (if one of them is in ${SRCS}, not just
if VFS_KLD is defined).

There are some complications to avoid using the "@" symlink before it
is built.

e902c1bb07 Add variable INSTALLFLAGS_EDIT used to remove arbitrary INSTALLFLAGS.
Specifically intended for removing -fschg ("INSTALLFLAGS_EDIT=:S/schg/uchg/")
this makes the NOFSCHG flag redundant.  NOFSCHG will still be honoured by
bsd.lib.mk but is valid for buildworld only.  NOFSCHG is still implemented in
the old way (ie. _not_ ".if NOFSCHG then { INSTALLFLAGS_EDIT+=:S/schg/,/ }"
to emphasize the fact that NOFSCHG is only supported in a limited
fashion and for buildworld.

The interface and implementation are such that future use of flags such
as sappnd can also be easily removed or altered (perhaps to uappnd).

2336a7ea75 Removed all traces of LN_FLAGS. It was only used to produce a link
/usr/sbin/sysctl -> ${DESTDIR}/sbin/sysctl in some versions of 2.2,
and this link was broken if DESTDIR was set.

Added a SYMLINKS macro.  This works the same as LINKS, except it
creates symlinks and the linked-to pathname may be relative.  This
is more flexible than LN_FLAGS, since it supports installing
symlinks independently of hard links.

Use `ln -f[s] ...' instead of `rm -f ...; ln [-s] ...' for LINKS and
SYMLINKS.  This is equivalent if the target is neither a directory nor
a symlink to a directory.

e0e2794cd8 Honor NOSHARED for tools. All tools should be built static for
`make world' to avoid problems with picking up (new) target or (stale)
host shared libraries.

Don't honor -static in LDFLAGS for linking LKMs.  LDFLAGS is not
actually for ld, but we use it anyway, and must prevent -static being
misinterpreted as -s.

Don't hide any of the link steps.

afba897ff2 Fixed `make depend', which I broke here about a month ago by moving
