rework patch model
At the Buildroot Developers Meeting (4-5 February 2013, in Brussels) a change
to the patch logic was discussed. See
http://elinux.org/Buildroot:DeveloperDaysFOSDEM2013
for details. In summary:
* For patches stored in the package directory, if
package/<pkg>/<version>/ does exist, apply package/<pkg>/<version>/*.patch,
otherwise, apply package/<pkg>/*.patch
* For patches stored in the global patches directory, if
$(GLOBAL_PATCH_DIR)/<pkg>/<version>/ does exist, apply
$(GLOBAL_PATCH_DIR)/<pkg>/<version>/*.patch, otherwise, apply
$(GLOBAL_PATCH_DIR)/<pkg>/*.patch
This patch adds the new BR2_GLOBAL_PATCH_DIR configuration item, and reworks
the generic package infrastructure to implement the new patch logic.
