Dear Maintainer,
On Loong64, NCG is currently not supported in 9.10, while Llvm backend
incompatible with tables-next-to-code, which will generate PLT for non-
function symbols.
Only lld can correctly link it.
Specifics can be seen: https://gitlab.haskell.org/ghc/ghc/-/issues/25531
And the 0005-* patch is also required for C files.
