Sometimes we need to re-run configure, due to changes in configure 
files. Make detects such changes and forces a new run of configure.

If configure was run with a long command line, it's tricky to get this 
right again. However, this can be done automatically by the Makefile.

By adding a new target 'reconfigure', if we have an existing 
configuration, configure will be ran again with the same arguments as 
last time.
