uncovering some interesting problems. Be conservative and effecitvely
disable this by default. Interested parties may still define
KERNBUILDDIR by hand to achive the same effect.
I plan on referting this change after 5.2 is released, or sooner if
the issues with building releases are resolved and re@ approves.

kernel build. This makes it possible for me not to get pissed off that
random.ko crashes the system trying to rdtsc() when the i386/cpu.h
support code decides it's okay to call that op when neither I386_CPU or
I486_CPU is defined. I guess it also makes WITNESS/INVARIANTS defines
get picked up by the modules.
no matter where in the directory structure it may be. Use this and the "-k"
flag in the generated gdbinit files so that the "getsyms" function in gdb
requires no user intervention to run and will find every module if they're
in the kernel build's module directory. This is still quite useful for
cases where gdb knows that the path for some modules is /boot/kernel and
others are in the object directory for /usr/src/sys/$ARCH/compile/kernel.

Always use sys/conf/kern.mk when building kernel/modules.
<bsd.kern.mk> is only preserved for sys/boot/pc98/boot2
for now, but this will be fixed. If there are other
users of <bsd.kern.mk>, please let me know.

is a compiler tool and needs to be compiled by the host compiler. I've
tested this in i386->sparc cross-build, 4.7->current upgrade, normal
buildkernel target, and normal /sys/i386/compile/GENERIC configurations.

under way to move the remnants of the a.out toolchain to ports. As the
comment in src/Makefile said, this stuff is deprecated and one should not
expect this to remain beyond 4.0-REL. It has already lasted WAY beyond
that.
Notable exceptions:
gcc - I have not touched the a.out generation stuff there.
ldd/ldconfig - still have some code to interface with a.out rtld.
old as/ld/etc - I have not removed these yet, pending their move to ports.
some includes - necessary for ldd/ldconfig for now.
Tested on: i386 (extensively), alpha
the environment for the last command of the pipeline (xargs) instead
of too early in the broken version or using an extra env process for
each command spawned by xargs as in rev.1.12. Fixed a nearby English
error.
-finstrument-functions instead of -mprofiler-epilogue. The former
works essentially the same as the latter but has a higher overhead
(about 22 more bytes per function for passing unused args to the
profiling functions).
Removed all traces of the IDENT Makefile variable, which had been
reduced to just a place for holding profiling's contribution to CFLAGS
(the IDENT that gives the kernel identity was renamed to KERN_IDENT).
to build kernel and kernel modules so stop supporting them in
bsd.subdir.mk and reimplement them in kern.post.mk and kmod.mk
as special versions of the install and reinstall targets, and
only define them if DEBUG is also defined (when debug versions
are really built).
Prompted by: bde
"env name=value ... cmd ..." is just a pessimized way of doing
"name=value ... cmd ..." in real shells. Set the environment
(without using env(1)) before starting xargs so that env(1)
is not needed in "xargs env name=value ... cmd ..."
lint, so this is turned off by default. Setting WANT_LINT will turn
on generation of lint libraries for /usr/libdata/lint/*.ln.
