Richard Levitte 8dd0ff1c55 Configure et al: cleanups
Remove some config attributes that just duplicate values that are
already there in other attributes.

Remove the special runs of mkdef.pl and mkrc.pl from build file
templates, as these are now done via GENERATE statements in
build.info.

Remove all references to ordinal files from build file templates, as
these are now treated via the GENERATE statements in build.info.

Also remove -shared flags and similar that are there in shared-info.pl
anyway.  (in the case of darwin, it's mandatory, as -bundle and
-dynamiclib don't mix)
