Ok. linuxthreads-old (the default) afaik works on ARM.

Yes, all *.patch

Strange. gcc 4.3.x works fine here on ARM. Maybe your problems are
caused by your uclibc changes?

Why would you want to use so old kernel headers? Didn't the make
headers_install target only get added to the kernel in 2.6.19?
