Try to avoid doubling the cppflags if rerun without removing config.sh
This bug has been here since 2001, introduced by yours truly
in 58e77565. Hasn't been too harmful, obviously. It doubles
the cppflags only once, thankfully, unlimited doubling would
probably have been noticed earlier.
The avoidance maneuver is far from fool-proof. To be more
fooler-proofer, some sort of order-preserving deduping would
be needed.
