Sorry about that.

asm-source is compiled with -nostartfiles. So gcc does not use libgloss.a.
But on m32r, somehow several system calls, _write, etc., are included
in it. So it is necessary to declare these symbols. On other architectures,
these system calls are included in libc.a, which is not removed
by -nostartfiles.

Unfortunately, I don't know why m32r's libgloss is different from others.
Should I modify libgloss and newlib rather than declare symbols in m32r.inc?
