The issue was reported by @xazax.hun here: https://reviews.llvm.org/D69825#1827826
"This patch (D69825) breaks scan-build-py which parses the output of "-###" to get -cc1 command. There might be other tools with the same problems. Could we either remove (in-process) from CC1Command::Print or add a line break?
Having the last line as a valid invocation is valuable and there might be tools relying on that."

LLVM triple normalization is handling "unknown" and empty components
differently; for example given "x86_64-unknown-linux-gnu" and
"x86_64-linux-gnu" which should be equivalent, triple normalization
returns "x86_64-unknown-linux-gnu" and "x86_64--linux-gnu". autoconf's
config.sub returns "x86_64-unknown-linux-gnu" for both
"x86_64-linux-gnu" and "x86_64-unknown-linux-gnu". This changes the
triple normalization to behave the same way, replacing empty triple
components with "unknown".
This addresses PR37129.

Summary:
This patch prevents OpenMP flags from being forwarded to CUDA device commands. That was causing the CUDA frontend to attempt to emit OpenMP code which is not supported.
This fixes the bug reported in https://llvm.org/bugs/show_bug.cgi?id=28723.
