Make building with LTO work on macOS
When building with -flto, the backend binary must keep many otherwise
unused symbols to make them available to dynamically loaded modules /
extensions. This has been done via -Wl,--export-dynamic on many
platforms for years. This flag is not supported by the macOS linker,
though. Here it's called -Wl,-export_dynamic instead.
Thus, make configure pick up on this variant of the flag as well.
Meson has the logic upstream as of version 1.5.0.
Without this fix, building with -flto fails with errors similar to [1]
and [2].
