-march=... currently works at configure time, but is replaced with -march=nehalem at build time under brew's superenv. This causes Open MPI build to fail under brew. This commit does pass the -march=... option that worked at configure time via the HOMEBREW_ARCHFLAGS environment variable. This is a bit hacky, but less suboptimal than simply not building the op/avx component (e.g. configure --enable-mca-no-build=op-avx) The suspicious superenv behavior has been reported at Homebrew/brew#10078.
