* __HAVE_SYSCALL_INTERN. If this is defined, e_syscall is replaced by
e_syscall_intern, which is called at key places in the kernel. This can be
used to set a MD syscall handler pointer. This obsoletes and replaces the
*_HAS_SEPARATED_SYSCALL flags.
* __HAVE_MINIMAL_EMUL. If this is defined, certain (deprecated) elements in
struct emul are omitted.
This gets most existing m68k a.out binaries working with m68k ELF
kernels.
There are still some remaining ABI issues to track down; most notably,
some ioctl(2) calls are affected by the change.
