[Mesa-dev] [PATCH 4/4] swr: automake: don't ship LLVM version specific generated sources

[Emil Velikov]

From: Emil Velikov <emil.velikov at collabora.com>

Otherwise things will fail to build, if the builder is using another
version of LLVM.

v2: annotate all the dependencies of builder_gen.h
v3: clean the generated files as needed
