Subject: Update macOS linker flags in GNUmakefile.llvm

`-flat_namespace` is effectively deprecated and doesn't really work as
expected these days. Omitting the `-flat_namespace` means that binaries
are built with a two-level namespace, which don't support
`-undefined suppress`.

The idiomatic way of telling the linker to look up undefined symbols at
runtime is using `-undefined dynamic_lookup`, which is supported by a
two-level namespace.
