'exec', not 'eval'.

Because it now does it a better way.

Instead of exec-ing configure, in order to get the config.nice file
closed before configure tries to re-write it, now configure moves the
old config.nice aside and writes a new one.

This has the benefit that the path to configure doesn't get made
absolute, thus constraining the use of the config.nice file to the
particular current directory.
