[Mesa-dev] swrast gallium provider doesn't work on Solaris SPARC (Mesa 20 with LLVM 10)

[Roland Scheidegger]

You can also set LP_DEBUG=tgsi_ir instead (but it will only work in
debug builds).

No idea though what could go wrong when using NIR, seems fairly strange
since there's nothing architecture specific in there (and the generated
IR should be fairly similar too especially for simple stuff).
