OpenBLAS: gcc4{5,6,7,8,9} variants seem to be brocken

[petrrr]

OpenBLAS provides various compiler variants, but the gcc seem to be at least for the tested versions 4.7, 4.8 and 4.9.

OpenBLAS @0.2.13 (math, science)
Variants:             [+]clang, gcc45, gcc46, gcc47, gcc48, gcc49, lapack, universal

Description:          OpenBLAS is an optimized BLAS library based on GotoBLAS2
Homepage:             https://github.com/xianyi/OpenBLAS

Build Dependencies:   dragonegg-3.3-gcc-4.8
Conflicts with:       OpenBLAS-devel
Platforms:            darwin
License:              BSD
Maintainers:          nicos@macports.org, openmaintainer@macports.org

The error reported boils down to:

[...]
/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_math_OpenBLAS/OpenBLAS/work/.tmp/ccKpAOjH.s:13:no such instruction: `vmovss (%rsi), %xmm0'
[...]

so it is likely to be related to #40592. If there is not intention to fix gcc compilation, these variants should probably be removed.

Thanks for the report. I had indeed left some flags which were preventing the options to be activated, and the build was made based on the native architecture whatever the options. This has been fixed in r132259 and r132260.
