Use a local copy of the source when building gcc-target (since
we hacked up the source used to build the cross compiler). Fix the crt1.o not found problems. It turns out gcc was thinking it was acting as a cross compiler, which is clearly not what we want here. With this, everything seems to be working nicely for both C and C++.
