The -Xoffload-linker command allows forwarding of linker commands to the clang-linker-wrapper used for linking offload libraries into the resulting offload binaries amongst other tasks. This is a rather useful command to have to support the offloading programming models flang-new currently aims to support (OpenMP/OpenACC). Currently this flag is utilised in the check-offload tests after a recent addition and is used in conjunction with the Fortran OpenMP test suite there, which fails at the moment due to flang-new not recognizing the command, this fixes the issue. The alternative to this would of course be to setup the test config to avoid using this flag with Fortran, but I believe adding support of the flag to flang-new has more merit as having the same compatability/communication capabilities as Clang to the clang-linker-wrapper is important as it's a critical component of the offload pipeline, and the command will likely see more use in the near future.
