[compiler-rt] [compiler-rt] allow building with uefi (PR #131499)

[Tristan Ross via llvm-commits]

https://github.com/RossComputerGuy created https://github.com/llvm/llvm-project/pull/131499

I'm trying to put together an LLVM built toolchain (including LLVM libc) targeting UEFI, currently I get an error saying "Unknown target". This PR enables compiling compiler-rt for UEFI.
