FSF GCC older than 4.7 does not accept -arch flags.

[mf2k (Frank Schima)]

So we should simply delete the gcc variants less than 47 and add gcc48 and gcc49.

[larryv (Lawrence Velázquez)]

We could also patch the build to use -arch or -mFOO as appropriate, with get_canonical_archflags.

Replying to larryv@…:

So...has this been tried? Is there any timeline for a patch?

Hi all, I guess #39351 is a duplicate of this and should be closed.

I can't seem to be able to reproduce this error. Is this still a problem?
