Add showfiles and showprods to platform specific commands

Implement run_configure and autoconf overrides
run_configure is a new platform specific way to do the configure step of
the build.
It was implemented to allow the use of the ac_overrides variable to easily
override autoconf settings which is needed on Irix.
run_configure will also run an automatic scan (using an external script
check_ac) of config.log for suspicious ac_cv_lib definitions.
The contents of ac_overrides will be added in the Configure part of the
relnotes.
Fixed the FIXME's regarding perl in auto_rel by replacing perl with awk.
Thanks to Laura Fairhead who posted that awk trick on usenet in 2001.
