Hi,

In commit r233654, Christian introduced a new test: pragma_cpp_fma.

Unfortunately, this test fails when gcc is configured --with-fpu >=
neonvfpv4: __ARM_FEATURE_FMA is still defined after the last
pop_options.

To address this, I propose to simply force fpu=vfp via a pragma at the
beginning of the test, like we do in several other similar tests.

OK?

Christophe.
