[bitbake-devel] [PATCH] cooker.py: multiconfig support for findBestProvider

[Juro Bystricky]

In a multiconfig environment, a tinfoil call such as

    tinfoil.parse_recipe("multiconfig:arduino-101-sss:gcc")

can fail with an error such as:

  File "/data/master/poky/bitbake/lib/bb/tinfoil.py", line 373, in get_recipe_file
    raise bb.providers.NoProvider('Unable to find any recipe file matching "%s"' % pn)
bb.providers.NoProvider: Unable to find any recipe file matching "multiconfig:arduino-101-sss:gcc"

The culprit is findBestProvider (only called from tinfoil), which does not
handle multiconfig. This patch fixes the error and the tinfoil call returns absolute path
to the recipe, i.e:

  "/data/master/poky/meta/recipes-devtools/gcc/gcc_6.3.bb"
