Yes, I tried gcc-4.5.1 and eglibc-2.16, it didn't work.

The following combinations didn't work:
gcc-4.5.1, eglibc-2.15, binutils-2.22
gcc-4.5.1, eglibc-2.16, binutils-2.22
gcc-4.7.2, eglibc-2.13, binutils-2.22

The combinations that worked are
gcc-4.5.1, eglibc-2.13, binutils-2.22
gcc-4.6.3, eglibc-2.13, binutils-2.22 (from the Denx ELDK 5.2.1 release.)

I am going to re-verify with the current poky, meta-openembedded/toolchain-layer to ensure that it too builds and works, with gcc-4.6.3 and eglibc-2.13.

We can't narrow it down to one component because
gcc-4.7.1 + eglibc-2.13 doesnt work, and
gcc-4.5.1 + eglibc-2.15 & egblic-2.16 don't work.

We've got two variables here, that are causing a failure in dynamic linking (probably).
