Not all compilers claiming to be gcc support this attribute.

It is possible that the compiler requires flags set by the --cpu
option, so we should not attempt to run it before those flags have
been added.

The auto-vectoriser in gcc is enabled by default at -O3 since version
4.3.  However, it provides no speed benefit, but does produce incorrect
code on many targets.  Disabling it for gcc should give more reliable
builds.

If the adventurous want it back, they can edit the makefile themselves.

If ff_neterrno() is checked instead of errno, that's probably what should be
used in the return value.
As a sideeffect, this gives better compatibility with Windows (CE), where
network errors aren't visible in errno.)
