Any particular reason why you aren't using the stable versions then?
(uclibc 0.9.30.1, gcc 4.3.x)

Seems like we need something like
toolchain/gcc/4.3.2/999-4.3.2-armeabi-aapcs-linux.patch for 4.2.x as
well.

4.1.20? That's old, what distribution are you on?

It's still on my todo list.

Do you have the same problem with the currently stable gcc/uclibc
versions? Please post your .config
