Kent Spillner points out that this last sentence is garbled. The
paragraph should read:
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.
I have updated it in my branch.
