Summary: The C library for GPUs provides the ability to target regular C/C++ programs by providing the C library and a file containing kernels that call the `main` function. This is mostly used for unit tests, this patch provides a quick way to add them without needing to know the paths. I currently do this explicitly, but according to the libc++ contributors we don't want to need to specify these paths manually. See the discussion in https://github.com/llvm/llvm-project/pull/104515. I just default to `lib/` if the target-specific one isn't found because the linker will handle giving a reasonable error message if it's not found. Basically the use-case looks like this. ```console $ clang test.c --target=amdgcn-amd-amdhsa -mcpu=native -startfiles -stdlib $ amdhsa-loader a.out PASS! ```
