All Makefiles now use MACHINE_ARCH for the target architecture.
Unification is required for cross-building.

usr.bin/gcore/Makefile:
fixed typo: MACHINDE -> MACHINE_ARCH
<sys/sysproto.h> and use them (so far only) in kern/init_sysent.c.
Don't put $Id in generated files.
kern/syscalls.master:
I had to add some new fields to describe some non-orthogonal names.
E.g., the args struct for the syscall-implementing function foo()
is usually named `foo_args', but for getpid() it is named `args'.
sys/sysent.h:
sy_call_t is still incomplete to hide a couple of warnings.
