Mesa attempts to disable llvmpipe on architectures where it isn't known 
to work (those that are not in LLVM_ARCHS in debian/rules), but in 
current versions this is ineffective because the build fails. In 
unstable:

>../meson.build:217:3: ERROR: Feature llvm cannot be disabled: R600 Gallium driver configured to require LLVM

and in experimental:

>../meson.build:224:3: ERROR: Feature llvm cannot be disabled: R300 Gallium driver requires LLVM for vertex shaders

Presumably this means that r300 and r600 should be moved from the 
generic Linux code path

  GALLIUM_DRIVERS += nouveau r300 r600 virgl

into the block that tests for LLVM_ARCHS. Perhaps a porter for one of 
the affected architectures could prepare a patch?
