[runtimes] Skip custom linker validation for gpu/offload targets (#189933)
This fixes `Host compiler does not support '-fuse-ld=lld'` error when
cross-build libclc for gpu target. Cmake configure command is:
-DRUNTIMES_amdgcn-amd-amdhsa-llvm_LLVM_ENABLE_RUNTIMES=libclc \
-DLLVM_RUNTIME_TARGETS="amdgcn-amd-amdhsa-llvm"
libclc targets only support offload target cross-build and can't link
host executable. The configuration error is false positive for offload.

This PR adds a baseline test to first check if the target can link
executable. If it fails (typical for gpu/offload), we skip the custom
linker validation.
