  Configure: do not check for an absolute prefix in cross-builds

The check is always made according to the host platform's rules, which may
not be true for true when the target platform is different, e.g. when
cross-building for Windows on a Linux machine. So skip this check when
used together with the `--cross-compile-prefix=` option.
