[testsuite] Fix SPARC testsuite gnu11 fallout

[Rainer Orth]

A couple of gcc.target/sparc tests were FAILing on Solaris/SPARC due to
the gnu11 change:

FAIL: gcc.target/sparc/20001013-1.c (test for excess errors)
FAIL: gcc.target/sparc/mnofpu.c (test for excess errors)
FAIL: gcc.target/sparc/sparc-ret.c (test for excess errors)
FAIL: gcc.target/sparc/ultrasp6.c (test for excess errors)
FAIL: gcc.target/sparc/ultrasp8.c (test for excess errors)

The following patch fixes them; tested with the appropriate runtest
invocation on sparc-sun-solaris2.11, will commit shortly.
