The linker issue is due to a bug in the way we find the path to the CRT
object files (crti.o, etc.). We were assuming that if /usr/lib64 exists,
that's where we would find the 64-bit versions. On Ubuntu 14.04, there is
a /usr/lib64, but that is not where the CRT object files live.
Here is the proposed fix (the change is just to the test after the 'elif'):
