The expected results for signbit-2 only arise on x86 with avx512f
disabled and sse2 enabled. The patch already disables avx512f
explicitly, but it fails to enable sse2.
Bootstrapped on x86_64-linux-gnu. Also tested on ppc- and x86-vx7r2
with gcc-12.
for gcc/testsuite/ChangeLog
* gcc.dg/signbit-2.c: Add -msse2 on x86.
