[PATCH wayland] build: Allow disabling building of wayland libraries

Fri Jun 12 13:01:24 PDT 2015


When cross-compiling it may be useful to build only the wayland-scanner
natively.  This patch makes it possible to disable build of the libraries.

This also allows us to relax some of the build requirements when compiling
just the scanner.
