But still, you have in your .config:

BR2_TOOLCHAIN_CTNG_CONFIG="toolchain/toolchain-crosstool-ng/crosstool-ng.config-uClibc"

which means that you are going to end up with a uClibc based toolchain. You 
need to put crosstool-ng.config-glibc or crosstool-ng.config-eglibc in there 
for a glibc/eglibc toolchain.

And what about the pre-built, eglibc based, Sourcery CodeBench toolchain?
