config.status logging to config.log

[Lars J. Aas]

A side-effect of the recent config.log-related changes in configure
caused config.status to stop logging to config.log (fd 5 is directed
to /dev/null in the beginning).

This patch re-initializes fd 5, but I've moved the config.log logging
parts till after having processed the command line options (to avoid
logging --version and --help invocations to config.log).

        * acgeneral.m4 (_AC_OUTPUT_CONFIG_STATUS):  Re-enable logging to
        `config.log' from `config.status', but delay logging till after
        command line option processing.
