Bug fix
Description:
Fix build on sparc64 platform for FreeBSD by modifying the config/gnu-flags
to not insert '-march=i686' on non-Intel platforms. (This change allows HDF5
to run correctly on all five of the main FreeBSD platforms... :-)
Platforms tested:
FreeBSD 4.9 (sleipnir)
h5committest not run since it's a FreeBSD-specific fix.
