this happens to you because xlocale.h has been removed from glibc
since version 2.26 so it's not available anymore in the version
shipped by current.
there are a few ways to workaround this but you shouldn't actually
need any: you don't install a separate libc++ in current because is
now provided as part of the llvm package.
