pgsql: Improve build-time check that libpq doesn't call exit(). - Mailing list pgsql-committers

Improve build-time check that libpq doesn't call exit().

Further fixes for commit dc227eb82.  Per suggestion from
Peter Eisentraut, use a stamp-file to control when the check
is run, avoiding repeated executions during "make all".
Also, remove "-g" switch for nm: it's useless and some versions
of nm consider it to conflict with "-u".  (Thanks to Noah Misch
for running down that portability issue.)
