I'm happy to commit this patch.

I checked that for non-LTO builds, this option does not change the
output binary, so it seems harmless in that sense.

An equivalent change has recently been merged into meson upstream, so
we'll get the same behavior on meson before long.

The argument "If you're going to manually inject -flto, seems like you
could manually inject -Wl,-export_dynamic too, so why do you need this
patch?" is true, but the behavior that the link fails unless you use
both options is pretty surprising, so this is a small quality of life
improvement. Also, it seems that LTO use is already in the wild, so it
seems sensible to make that easier to exercise during development too.
Maybe a configure --enable-lto option would be sensible, but that can be
a separate patch.
