    configure: restore backward compatibility

    Commit a9c3d70d902a0473ee5c13336317006a52ce8242 broke backward compatibility
    by making 'configure' error out if parameters are passed, instead of
    ignoring them.
    Sometimes packaging systems detect 'configure' and assume it's from
    autotools, and pass a bunch of options. Eg:

     dh_auto_configure
            ./configure --build=x86_64-linux-gnu --prefix=/usr --includedir=${prefix}/include --mandir=${prefix}/share/man --infodir=${prefix}/share/info --sysconfdir=/etc --localstatedir=/var --disable-option-checking --disable-silent-rules --libdir=${prefix}/lib/x86_64-linux-gnu --runstatedir=/run --disable-maintainer-mode --disable-dependency-tracking

    Ignore unknown options again instead of erroring out.

    Fixes: a9c3d70d902a ("configure: add options ability")
