Well, it's only important on platforms where we can't restrict
libpq.so from exporting all symbols. I don't know how close we are
to deciding that such cases are no longer interesting to worry about.
Makefile.shlib seems to know how to do it everywhere except Windows,
and I imagine we know how to do it over in the MSVC scripts.

Ah, yeah, updating MacPorts again brought in meson 1.2.1 which seems
to work. I now see a bunch of
ld: warning: ignoring -e, not used for output type
ld: warning: -undefined error is deprecated
which are unrelated. There's still one duplicate warning
from the backend link:
ld: warning: ignoring duplicate libraries: '-lpam'
I'm a bit baffled why that's showing up; there's no obvious
double reference to pam.
