modula-2, libm2min: Declare abort and exit as expected.

The build is currently emitting a warning that abort() is declared differently
from the built-in.  This updates the declaration to match expectations.

Signed-off-by: Iain Sandoe <iain@sandoe.co.uk>
gcc/m2/ChangeLog:

	* gm2-libs-min/libc.c (abort): Update declaration to match the
	expected form, add no-return attribute.
	(exit): Add no-return attribute.
