Use return instead of exit() in configure
Using exit() requires stdlib.h, which is not included. Use return
instead. Also add return type for main().
This back-patches commit 1c0cf52b3
into out-of-support branches,
pursuant to a newly-established project policy that we'll try to keep
out-of-support branches buildable on modern platforms for at least
ten major releases back, ensuring people can test pg_dump and psql
compatibility against servers that far back. With the current
development branch being v15, that works out to keeping 9.2 and up
buildable as of today.
This fix is needed to get through 'configure' when using recent
macOS (and possibly other clang-based toolchains). It seems to
be sufficient to get through 'check-world', although there are
annoyances such as compiler warnings, which will be dealt with
separately.
