gmp @5.0.1 fix for i7 MacBook Pro

[nils.ohlmeier@…]

gmp @5.0.1 still fails on configure on a recent MacBook Pro, because config.guess identifies the CPU as i386. The attached patch adds the CPU id of the i7 to the list of know CPU's of gmp's config.guess.

Patch which adds i7 CPU id to config.guess

Lame patch of the gpm @5.0.1 Portfile to include the i7 patch

Please remember to cc the maintainer.

There's already code in place that's meant to work around this, so it would be good if we could figure out why it isn't working for you. Please start by attaching the log.

After trying to reproduce the problem it turns out the build fails only if I use the universal variant. So without any special flags the existing patch seems to work, but when I try to compile with universal I get this:

Should be fixed in r77717.

The code meant to work around this does not run when universal is set.
Recognizing Sandy Bridge is probably a better fix since it allows more processor dependent code to be used.

Thanks for the patch.
