postgresql: avoid AC_TRY_RUN when testing snprintf()

Browse Source 
A few snprintf() compatibility tests in config/c-library.m4 use AC_TRY_RUN
that doesn't work for cross compilation. As a result configure.in decides to
build a bundled implementation of snprintf(). This implementation calls
isnan(), but -lm is missing. This breaks link with libpq.so. Preseed the
correct values to make the configure script happy, and fix rsyslog build.

Fixes:
