New subject: [OS-BUILD PATCH 1/4] Remove unpackaged kgcov config files
From: Don Zickus <dzickus(a)redhat.com>
Remove unpackaged kgcov config files
The kgcov option is applied as a partial snippet in the spec file. The
generated kernel-*-kgcov.config are not packaged and therefore unused.
My motivation here is because they conflict with the CLANG options when
I overlay the CLANG options on the gcov config file. Instead of special
casing them, let's just drop them.

New subject: [OS-BUILD PATCH 2/4] Apply partial snippet configs to all configs
From: Don Zickus <dzickus(a)redhat.com>
Apply partial snippet configs to all configs
There is a macro all_arch_configs that tries to optimize what configs we
apply the partial snippets to. While it speeds up things up a bit, it
creates conflicts with CLANG options. The process_configs.sh script
still processes _all_ the arches and expects the CLANG options to be set
correctly.
I can either add in an arch specific option to process_configs.sh to
only process the configs the correct CLANG snippet was applied to _or_
just apply the snippets to _all_ the configs.
The latter is easier so that is what this change does. The cost is an
extra second to apply the snippets to more config files.

New subject: [OS-BUILD PATCH 3/4] Add clang config framework
From: Don Zickus <dzickus(a)redhat.com>
Add clang config framework
Compiling for clang is getting trickier to do because the configs are
different than gcc in some cases. Mimic the kgcov framework (which uses
priority files) to setup clang to be easier to update their configs.
This leads to strange cases where clang debug configs need different
settings than clang non-debug configs. The priority.snip can handle the
variety of partial snippets for variants and arches well, the
kernel.spec needed to be updated to apply it reasonably.
I created a generic partial snippet loop that focuses on arch and
non-debug vs debug. This required adding debug options to
priority.snip. Once implemented it is a matter of collecting the
snippets and applying them based on arch and debug. This should provide
a variety of flexibility for teams like clang and make it easier to roll
in config changes based on which compiler is used.
