Comment (by leif):

 It seems GMP-ECM('s `configure`) no longer supports `--disable-asm-redc`,
 but only `--enable-asm-redc=no` (for whatever reason, haven't investigated
 why).

 FWIW, I immediately get "Illegal instruction" in `make check` regardless
 of the setting; this is with an older svn version of `clang` though (clang
 version 3.1 (trunk 155201)).
