Subject: [PATCH 1/1] configure: hack out old GCC-4.x test.

The Givaro ./configure script fails to detect modern versions of GCC,
instead deciding that they must be gcc-4.8. As a result, we wind up
with "-fabi-version=6" in CXXFLAGS, which then gets propagated to
users of "givaro-config --cflags", like fflas-ffpack.

This is already fixed upstream, but not in a release, and not in a
way that I care to backport. Here we just hack the configure script
directly since the change is so trivial.
