Right now, it is hard to have makefile-specific flags.

Add 'set -x' to configure, and figure how how the test is working in
configure. Look at the configure output. It shows how it is setting
those flags.

Added to TODO:
* Make Absolutetime/Relativetime int4 because time_t can be int8 on some ports
