Finally getting buildworld to work again...
More problems in the kernel though. ucontext_t is used as a
parameter to sigreturn (and getsetcontext soon), so it is
referenced in <sys/sysproto.h>. Lots of stuff includes
<sys/sysproto.h>. Do we,
a) Include <sys/ucontext.h> conditionally from
<sys/signal.h> based on _KERNEL, or
b) Change makesyscalls.sh to emit #include\t<sys/ucontext.h>
when generating sysproto.h, or,
c) Add includes for <sys/ucontext.h> to all files that
include <sys/sysproto.h>
