The end of config.log often contains expected error messages completely 
unrelated to the actual problem.

Debian autobuilders already dump config.log when when configuring failed,
and there it is a common problem that people end up searching for the 
problem in the wrong places due to that.

If possible, it would therefore be better to make it accessible separately.
