Subject: configure: Use WAYLAND_SCANNER_RULES only if available
X-Git-Tag: 062012170305~1869
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=412042523e80ddb19196851b6e729238b5cc0609;p=profile%2Fivi%2Fmesa.git

configure: Use WAYLAND_SCANNER_RULES only if available

This has the drawback that when creating configure for
distribution, wayland needs to be available for the packager.

Also the the macros has the wayland prefix hardcoded, so
we cant copy it in mesa right now.
