Make the mpfr formula look and behave more similar to the somewhat related gmp formula.

Additionally I come across the following error when installing with superenv
(IOW: when installing with --env=std it compiles just fine)
clang: error: unable to execute command: Segmentation fault: 11
Can you reproduce the error?

My research revealed that the following workaround prevents the sigsegv:
inreplace "configure", "${wl}-flat_namespace ${wl}-undefined ${wl}suppress", ""
How is this related to superenv?

I get a similar error with mpfr

Edit: I should add that this has only occurred for me when trying to upgrade mpfr as a dependency for libmpc. Don't know if libmpc has anything to do with this or not...

happens to me too, just upgrade xcode to 4.5

I have Xcode 4.5 and the issue remains

I'm not really a fan of adding more skip-check options for things like this. I think it encourages sacrificing correctness for minimal gain. The test suite doesn't take that long to run, and gmp, mpfr, and libmpc are all things that run a high risk of miscompilation.

@jacknagel Good point how about removing the --skip-check option from gmp then? ;)

Totally in favor of that.
