set the specfile - if no argument has been given then check whether the ac_unique_file looks like a .spec file and use it. This macro is ac_REQUIRED by many AX_SPEC_ routines.

the AX_SPEC_EXTRACT macro is a helper used by many AX_SPEC_ routines and therefore placed here to be automatically included in the macro set of (older) aclocal/acinclude.
