This one didn't even assemble on AOUT targets due to lack of .section,
and broke on COFF targets due to limitation in section name length.
AOUT targets still fail after fixing the assembly problem since the
format doesn't really allow arbitrary section addresses, so disable
the test entirely for AOUT.

	* ld-scripts/defined.exp: Don't run defined5 for AOUT.
	* ld-scripts/defined5.s: Use .text for "defined" section.
	* ld-scripts/defined5.t: Adjust.
