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.
