You need more than that, you need all of the sysroot libraries on the 
target.

The last time I looked at buildroot in 2010 it was still incorrectly 
copying the sysroot for a multilib'd toolchain and required patching.

You don't have to patch buildroot, you just need to copy the correct 
sysroot to the target as a post-build step.
