Different moment to check for them:

- PKG_CHECK_MODULE check presence when running ./configure
- m4_ifndef when autoconf is executed.

If you build autotools for the package on a system that has no
xorg-server installed, you'll receive a broken configure script, thus
why I wanted to make it explicit that you need to have it around at
autoconf time.
