You should be able to influence that by specifying -Ddarwin_sysroot=...

Yea, it seems decidedly not great.

A third approach would be to make sure we don't include xlocale.h from
pg_locale.h. IMO pg_locale currently exposes too many implementation details,
neither xlocale.h nor ucol.h should be included in it, that should be in a C
file.
