The GPL license seems preferable in this case, which is a point in favor of GCC. A major performance consideration comes when there are a lot of lib files as well as -debug. This difference will come down to the linker, and seeing as `lld` can be a drop-in replacement for `ld`, and added independently of Clang, it is not a major point in favor of Clang. We can simply install `lld` from the LLVM backend (Clang is just the frontend), and pass the `-fuse-ld=lld` flag to GCC to make it use `lld` instead of `ld`.
