Attempting to install glibc configured with --prefix=/usr into
a non-standard directory specified by the prefix make variable fails with an error. Since this is an unsupported use case, this change makes make install fail early and with a descriptive error message when either the prefix or the exec_prefix make variable is overridden on the command line.
