AFAIK that 'feature' is there to support configuring a 'tree'
of projects (like gcc), where subprojects have their own configure
scripts with different options. That way you can give all options
to top-level configure script which passes them to other scripts and
each picks only whats needed. In such setting all scripts need to
ignore unknown options.
As PostgreSQL tree is not set up that way, I think for clarity sake
it would be better to give explicit errors for unknown options.
