Just echoing what David said really, but: if the libgcc changes
are expected to be portable beyond glibc, then the existence of
an alternative option for glibc shouldn't block the libgcc changes.
The two approaches aren't be mutually exclusive and each approach
would achieve something that the other one wouldn't.
