Thanks. Its kind of a moot point because the assembler is down level.
It could not assemble SHA even if we could somehow point GCC to it.

But the suggested solution does not scale. We cannot ask thousands of
users to build a compiler. That's why we wanted to ask GCC to use a
different assembler in one place.
