Comment (by nkpart):

 The gcc command that it fails on is this:

 {{{
 gcc -E -undef -traditional -m64 -fno-stack-protector -m64 -I
 utils/genprimopcode/dist/build -I utils/genprimopcode/dist/build -I

 }}}

 I can run that command outside of the build and replicate the failure (as
 long as I change the `-o`).

 It fails with gcc-4.2 and gcc-4.8.

 However, it works with clang. Does the build try and guess if I've got
 fake clang gcc or apple-gcc installed? Could it be getting that wrong?
