This is when building libgcc.  It means that the newly built gcc is
unable to build an executable which runs on the current system.  An
error like "Bad CPU type" suggests a problem with the assembler or with
how gcc is invoking the assembler.  I don't know enough about Darwin to
know what is happening.
