Comment (by vbraun):
I agree, gcc just assumes that sufficiently recent binutils are installed.
So we really would need to also bundle binutils and its required BFD and
opcodes libraries, plus whatever else they use. It was probably a mistake
to use a cutting-edge gcc binary, we should use one that is as old as
possible while having all critical bugs fixed. Or have some framework for
CFLAGS that is smart enough to not turn on SSE levels that the assembler
does not support.
I'm fine with closing this ticket and fixing the SLES problems in the next
release (and on another ticket).
