testsuite: Fix -m32 gcc.target/i386/pr102464-vrndscaleph.c on RedHat.
This patch fixes the 4 FAILs of gcc.target/i386/pr192464-vrndscaleph.c
with --target_board='unix{-m32}' on RedHat 7.x. The issue is that this
AVX512 test includes the system math.h, and on older systems this provides
inline versions of floor, ceil and rint (for the 387). The work around
is to define __NO_MATH_INLINES before #include <math.h> (or alternatively
use __builtin_floor, __builtin_ceil, etc.).
