While the syscall table is indeed outdated (the lchown32/chown32 swap
isn't in there, and it just totally gets lost after around syscall 220),
the root cause is a missing __NR_exit_group declaration in defs.h.
Patch attached FYI; please note that this will generate a
linux/syscallent.h.m68k suitable for compilation; I still need to merge
the changes back into linux/syscallent.h proper, or add a linux/m68k
subdir. With these changes applied, the compilation at least progresses
beyond the earlier failure.
A point I'm not clear on: is the inclusion of __NR_exit_group or
SYS_exit as real syscall no in the defs really necessary? powerpc also
calls the same function on both exit and exit_group, but doesn't pass the
real syscall number to the strace handler function.
