llvm8, llvm9: secureplt patch fixes for ppc/ppc-musl
https://github.com/void-linux/void-packages/pull/15164

Description:
Bumps are necessary because this affects cross-compilers.

We need these patches in for the Rust 1.38 pull request to work correctly later. It's already confirmed to work on my side. The Rust PR will be using llvm8 because llvm9 generates broken executables on some targets with rust right now (regardless of how llvm9 is patched, so I already ruled this patchset out; it's an issue somewhere else) but llvm9 needs patching too (this potentially affects clang and so on), so do it at once.
