WRKSRC. LIBTOOL_OVERRIDE defaults to "libtool */libtool and */*/libtool,"
meaning that, in most packages, there's no need to set it.
So: Nuke tons of LIBTOOL_OVERRIDE=${WRKSRC} and adjust a few
SHLIBTOOL_OVERRIDEs (remove ${WRKSRC} from them).

Extended Affix Grammars (EAG) are an attempt to implement a very general form
of Affix Grammars, with very few restrictions. EAG can be used as a
specification formalism, specifying in general relations rather than functions,
or as a relational programming language similar in many respects to PROLOG.
