Look at crosstool: http://www.kegel.com/crosstool, there is a patch
(by me) to allow the building of toolchain with uClibc. You might (may/will)
have to make some changes, but it could serve as a basis.

If I were you, I'd try to build a toolchain with recent tools (latest buildroot
is OK for that), build a small static program (Hello world) and check it works.
Then, try to have both libc version along side (check names don't clash),
build your small program with dynamic loading and check it works.
Once you're there, you can add bigger programs.
