[Bug regression/24819] New: glibc math tests miscompiled with gcc-4.1

["olh at suse dot de" <gcc-bugzilla at gcc dot gnu dot org>]

make check fails with -O2 on powerpc64-linux and powerpc-linux with gcc-4.1
Works ok with gcc-4.0, and also with 4.1 and -O1.

ppc64:
make[2]: *** [/usr/src/packages/BUILD/glibc-2.3/cc-nptl/math/test-float.out]
Error 1
make[2]: *** [/usr/src/packages/BUILD/glibc-2.3/cc-nptl/math/test-double.out]
Error 1
make[2]: *** [/usr/src/packages/BUILD/glibc-2.3/cc-nptl/math/test-ifloat.out]
Error 1
make[2]: *** [/usr/src/packages/BUILD/glibc-2.3/cc-nptl/math/test-idouble.out]
Error 1
make[1]: *** [math/tests] Error 2

ppc:
make[2]: *** [/usr/src/packages/BUILD/glibc-2.3/cc-nptl/math/test-float.out]
Error 1
make[1]: *** [math/tests] Error 2

(make check runs without -k on ppc, the failure rate might be the same as on
ppc64).

Will post details and possible a testcase, later.
