Hello, Rodolfo.

I have been using mipsel-linux-uclibc-gcc 3.4.2 with binutils
2.15.91.0.2, and I have no
-allow_branch_to_undefined in this toolchain.  I patched
cpu/mips/start.S to set up the GOT
gp earlier, and used jal instructions to get to memsetup and the other
subroutines called there.

I also had to do a runtime calculation of the GOT offset.  I don't have
a clean patch right now.

I also have a driver for the SMSC LAN911x ethernet interface to
contribute.
