Peter Eisentraut 73275f093f 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].
