Reverted nacl_LIB_tc_root variables to old locations.
Reverted nacl_LIB_tc_root variables to old locations.

When I reverted the gyp intermediate directories, I forgot to change the
nacl_glibc_tc_root variable because it was already in a CL waiting to be
landed. This CL changes the variable to the original location.
