I use gcc setup to cross compile for uclinux.  Currently I use gcc 4.3.3
to compile for m68knommu.  It works very well.  Versions prior to 4.3
are practically unusuable though.

A gcc meant to generate glibc binaries for linux probably can't target
a uclibc linux for the same hardware.  I wouldn't expect it to.
