Comment(by vinc17@…):

 FYI, I tried trapping SIGILL in the past, but this didn't fix the problem
 (I suppose that the kernel doesn't have a way to know that SIGILL is
 trapped...).

 Now, I'm wondering... What MacPorts is supposed to do concerning binaries?
 Produce binaries that can only run on the local machine? But in such a
 case, this is a bit contrary to universal support. Or produce binaries
 that can run on any declared architecture? For instance, any PowerPC-based
 machine if PowerPC is declared. In the latter case, GMP's config.guess
 should be patched to avoid particular CPU detection (as a side effect,
 this would avoid the crash in config.guess). One could test to see whether
 binaries would be significantly slower.
