Subject: [PATCH 1/1] configure.ac: don't append -fabi-version=6 to CXXFLAGS.
This is a quick hack to avoid appending -fabi-version=6 to CXXFLAGS.
Both givaro and fflas-ffpack have problems with this legacy cruft
that are fixed upstream but tough to backport. We don't support
compilers that old, so we can just delete it.
