[PATCH, testsuite] XFAIL -fpic related failures for SPU

["Ulrich Weigand" <uweigand at de dot ibm dot com>]

Hello,

support for position-independent code on the SPU is limited because the
run-time environments do not support applying load-time relocations.
GCC therefore will error when building an application with -fpic that
would require such relocations (e.g. when a static initializer refers
to a symbol address).

This error triggers in a number of test cases.  As this can really be
considered a bug (but one that will not get fixed any time soon), I've
simply XFAILed all such tests.  (Except for g++.dg/opt/vt1.C, which
needs to be skipped as it has a scan-assembler clause that will ERROR
because the assembler file was not generated, even if the test is
XFAILed ...)

Tested on spu-elf with no regressions, fixes the FAILs.

OK for mainline and the 4.3 branch?

Bye,
Ulrich


ChangeLog:

	* gcc.dg/pr28243.c: XFAIL on SPU.
	* gcc.dg/torture/pr25947-1.c: Likewise.
	* gcc.dg/20030702-1.c: Likewise.
	* g++.old-deja/g++.other/comdat5.C: Likewise.
	* g++.old-deja/g++.other/local-alloc1.C: Likewise.
	* g++.dg/opt/vt1.C: Skip on SPU.
