I've been using this hack to work around the Linux/sparc64 compile failure described in Issue #47994 <https://github.com/llvm/llvm-project/issues/47994>, especially since the underlying glibc PR build/27558 <https://sourceware.org/bugzilla/show_bug.cgi?id=27558> doesn't seem to be making progress and some fix is required to have LLVM build on `sparc64-unknown-linux-gnu` at all, as evidenced on the buildbot.

I don't expect this patch to be commited, just posting for reference.

Tested on `sparc64-unknown-linux-gnu`.
