* Add recipe for version 0.29.1.
* Use the runConfigure wrapper.
* Use exact copy of the patchset for 0.29 as there are no offset
mismatches.
For 0.27.1:
* Call configure wuth "--with-pc-path" instead of "--with-pc_path".
For 0.28:
* Several changes to make it build and look almost like 0.29.1.
For 0.29:
* Switch to runConfigure in order to prevent pkg-config on secondary
arch from shadowing that of the primary arch.
For 0.27.1, 0.28, 0.29 and 0.29.1:
* Fix COPYRIGHT.
* Update HOMEPAGE and SOURCE_URI to avoid "301 Moved Permanently".
