The current uClibc version in CVS has known shared library loader
issues (I know I have broken mips and arm).  I'm still working on
fixing that up.

Odd.  uClibc 0.9.26 should work fine...

I notice you have not mentioned gcc and binutils at all.  Could
you share the details of your toolchain?  The fact you are
getting illegal instruction errors does case a bit of suspicion
on your toolchain.
