Fix his mistake here.

good reason a Gawk update takes an order of magnitude more effort than
it should...
Fix it by putting back the link of machine to sys/i386/include rather
than ../../include (aka sys/pc98/include). I had a stale machine link
on my first test.
Not sure what the "right" fix is, but this unbreaks things.
new files: kern.pre.mk, which contains most of the definitions, and
kern.post.mk, which contains most of the rules.
I've tested this on i386 and pc98. I have had feedback on the sparc64
port, but no reports from anybody on alpha, ia64 or powerpc. I
appologize in advance if I've broken you.

This also has the effect of fixing a typo that was in the last
version I committed.
as suser_td(td) works as well as suser_xxx(NULL, p->p_ucred, 0);
This simplifies upcoming changes to suser(), and causes this code
to use the right credential (well, largely) once the td->td_ucred
changes are complete. There remains some redundancy and oddness
in this code, which should be rethought after the next batch of
suser and credential changes.
in vfs_syscalls.c. Although it did save some indirection, many of
those savings will be obscured with the impending commit of suser()
changes, and the result is increased code complexity. Also, once
p->p_ucred and td->td_ucred are distinguished, this will make
vfs_mount() use the correct thread credential, rather than the
process credential.
debug another process based on their respective {effective,additional,
saved,real} gid's. p1 is only permitted to debug p2 if its effective
gids (egid + additional groups) are a strict superset of the gids of
p2. This implements properly the security test previously incorrectly
implemented in kern_ktrace.c, and is consistent with the kernel
security policy (although might be slightly confusing for those more
familiar with the userland policy).
o Restructure p_candebug() logic so that various results are generated
comparing uids, gids, credential changes, and then composed in a
single check before testing for privilege. These tests encapsulate
the "BSD" inter-process debugging policy. Other non-BSD checks remain
seperate. Additional comments are added.

really be moved elsewhere: p_candebug() encapsulates the security
policy decision, whereas the P_INEXEC check has to do with "correctness"
regarding race conditions, rather than security policy.
Example: even if no security protections were enforced (the "uids are
advisory" model), removing P_INEXEC could result in incorrect operation
due to races on credential evaluation and modification during execve().
