Yes, I did add /opt/crosstools/bin, containing mipsel-linux-as, etc. to
PATH. But I do not completely understand why failure to add binutils to
PATH would lead to xgcc invoking /usr/bin/as rather than complaining
that it cannot find mipsel-linux-as.

Great. My actual goal is to have a uClibc based toolchain but knowing
how to compile glibc for mipsel would help a lot already I hope.

Thanks,
