Clang 18 as of 2024-01-06 has some trouble with a construct in llvm 10's
Optional.h header, resulting in errors building devel/llvm10:

A similar issue has been reported to llvm upstream, but it is not clear
yet whether this is a clang regression or an intended behavior. In the
mean time, we can apply
https://github.com/llvm/llvm-project/commit/90cfbb81674ec to make the
port build with clang 18, as a workaround.
