Quote variables in -z tests correctly in wx-config.

The changes of r69944 broke wx-config for the traditional Unix systems (at
least Solaris and AIX, probably others too) which don't support using -z
without any value (unlike Linux/bash).

Fix this by quoting the possible empty variables in the tests.
