[autoconf 2.49e] configure --help creates config.log

[Rainer Orth]

I've just noticed that a configure script created by autoconf 2.49e creates
config.log in it's current working directory even when only invoked as
configure --help.  This shouldn't happen, since it will create a file even
if run in the source directory as ./configure --help, but the source
directory should be considered as read-only.
