[bitbake-devel] [PATCH 2/2] cache: Set packages for skipped recipes

[Robert Yang]

The provides and rprovides had been set for skipped recipes, packages are
similar to them (all of them provide something), so also set it. This makes it
easier to figure out the RDEPENDS issues, for example, lmsensors
(lmsensors_3.5.0.bb) RRECOMMENDS lmsensors-config-fancontrol
(lmsensors-config_1.0.bb), but lmsensors-config is skipped for some reasons,
then if we run:

$ bitbake lmsensors
ERROR: Nothing RPROVIDES 'lmsensors-config-fancontrol' (but /path/to/lmsensors_3.5.0.bb RDEPENDS on or otherwise requires it)
NOTE: Runtime target 'lmsensors-config-fancontrol' is unbuildable, removing...
Missing or unbuildable dependency chain was: ['lmsensors-config-fancontrol']
ERROR: Required build target 'lmsensors' has no buildable providers.
Missing or unbuildable dependency chain was: ['lmsensors', 'lmsensors-config-fancontrol']

We had no way to know who rprovides lmsensors-config-fancontrol, we can figure
it out by bitbake/contrib/dump_cache.py after this patch.
