This makes it much easier to find a particular thing in config.log.
We have to use the ${BASH_LINENO[*]} syntax which is a syntax error in
other shells, so test what shell we are running and use eval.
The extra output is only printed if configure is run with bash. On
systems where /bin/sh is not bash, it is necessary to say bash
./configure to get the extra debug info in the log.
