Conflict between BBCLASSEXTEND and named recipes.

[Jeremy Puhlman <jpuhlman@mvista.com>]

There seems to be a bug with available providers when a recipe file
provides the same name as an extended recipe. The extended version of
the recipe does not seem to be available at all.

Example:

If zlib_1.2.6.bb exists in a layer, with BBCLASSEXTEND="native
zlib-nativesdk" defined, and zlib-native_1.2.5.bb exists, the version
1.2.6 of zlib-native is not selectable at all.


bitbake -s | grep zlib
zlib                                                :1.2.6-r0
zlib-native                                         :1.2.5-r0
zlib-nativesdk                                      :1.2.6-r0

Even with PREFERRED_PROVIDER_zlib-naitve = 1.2.6 the results are the
same. I have been poking around the parser, but really haven't made any
progress, figured I would poke the list.
