- fix WITH_CTF when specified in /etc/src.conf [1]
- CTFCONVERT_CMD=... is a hack (should be defined to empty string instead):
make(1) should be taught to ignore empty commands silently in compat mode
(as it does in !compat mode, GNU make also silently ignores empty commands)
and to skip printing empty commands in !compat mode
- config(8) should generate ${NORMAL_CTFCONVERT} invocation without '@':
this will allow to simplify kern.pre.mk even more and lessen the number
of shell invocations during kernel build when CTF is turned off
- WITH_CTF can now be converted to usual MK_CTF=yes/no infrastructure

Backwards compatibility hacks to allow kernels to be built via config
wihtout updating world (good transition aide for -current, but also
allows kernels to be built on -stable the old way too). This likely
should go away around FreeBSD 10.0 or so.

Add an x86/include directory to the kernel to hold headers that are common
to amd64, i386, and pc98. The headers are installed to /usr/include/x86
during an installworld, and an 'x86' symlink is created for kernel builds
similar to 'machine' so that the headers can be included as <x86/foo.h>.

WITH_CTF can now be specified in src.conf (not recommended, there
are some problems with static executables), make.conf (would also
affect ports which do not use GNU make and do not override the
compile targets) or in the kernel config (via "makeoptions
WITH_CTF=yes").

Additional (related) changes:
- propagate WITH_CTF to module builds
- do not add -g to the linker flags, it's a noop there anyway
(at least according to the man page of ld)
- do not add -g to CFLAGS unconditionally
we need to have a look if it is really needed (IMO not) or if there
is a way to add it only when WITH_CTF is used

Note: ctfconvert / ctfmerge lines will not appear in the build output,
to protect the innocent (those which do not build with WITH_CTF would
see the shell-test and may think WITH_CTF is used).

Always compute the root of the kernel source tree and explicitly pass it
to module builds. This avoids having to have the module builds walk up

build to succeed when a new level of module subdirectories is added without
requiring that the /usr/share/mk/bsd.kmod.mk file on the machine be patched.
