[committed] Make pr24341.sh unsupported test more precise

[Tom de Vries <tdevries@suse.de>]

Hi,

When testing on SLE12SP4 aarch64, I ran into a pr24341.sh FAIL.

The FAIL was caused by the multifile containing .debug_info.  This in itself
is not incorrect, and it really means the test is unsupported.

Fix this by:
- adding a mechanism to dwz-tests.exp to handle a return code 77 as
  unsupported ( Similar to the skipped test return code in script-based
  automake tests).
- making pr24341.sh return 77 if the multifile contains .debug_info

Committed to trunk.

Thanks,
- Tom

	* testsuite/dwz.tests/dwz-tests.exp: Handle return code 77 as
	unsupported.
	* testsuite/dwz.tests/pr24341.sh: Mark unsupported if the multifile
	contains .debug_info.
