Can you attach the contents of your /proc/cpuinfo file? It seems like glibc is choosing the wrong library for accelerated memcpy maybe?
BTW, instead of building your own glibc, consider using the existing debug symbols for the regular eglibc build in Ubuntu. See https://wiki.ubuntu.com/DebuggingProgramCrash for details.
