But in that case we only need to build one set of libraries (ie, we don't
need separate host, build & target).

Just as important -- we can't necessarily proper multilib when building
with cc since the options necessary to create specific sets of libraries
are likely going to be different from what gcc thinks they should be.

OK.  I see what you're getting at.  At least for now I think we need to
keep the host, build & target libraries separate.
