UNREG: ignore -fllvm (Trac #13495)
Unregisterised GHC can only use C as a target backend
(option used to be called -fvia-C). -fasm option was
ignored with a warhing, but not -fllvm.
jms noticed the failure when tried to use quick-cross
build flavour. quick-cross enables -fllvm in makefile.
"inplace/bin/ghc-stage1" ... -fllvm
ghc-stage1: panic! (the 'impossible' happened)
(GHC version 8.0.2 for powerpc-unknown-linux):
LlvmCodeGen.Ppr: Cross compiling without valid target info.
This change ignores -fllvm as well.
