Ah, but you only specified it for glibc.  For gcc, you need to add something like

GCC_EXTRA_CONFIG="--with-cpu=mips32"

to au1550_mipsel.dat.

Let me know if that helps.

Also, would mipsel-au1550-linux-gnu be an ok target name,
or is there an established convention already for how
to name au1550 targets?
