[uClibc] Anyone using MIPS shared libraries?

[Mark S. Mathews]

Just for completeness:

It's pretty old, but here's a description of the sharedlib uclibc 
toolchain I've run successfully against a couple of MIPS targets (AMD 
and Toshiba):

gcc-3.2.2-uClibc-0.9.19-binutils-2.13.2.1-linux-2.4.18-mipsel

As I recall, I built it using the old pre-buildroot crosstools stuff.
