While it further breaks RPM building, all AC_SUBST(HAVE_*) have been nuked.
When AM_SUBST_NOTMAKE, tell automake to not generate var = @var@ in
Makefile.in for qf specific vars (QF_SUBST is a wrapper for AC_SUBST that
also calls AM_SUBST_NOTMAKE).
And fix the macro's spelling, too :)
QF_PROCESS_NEED_subroutine needs too much knowledge to get the prefix
riight every time. Much easier to set it at invocation.
QF_PROCESS_NEED has been renamed to QF_PROCESS_NEED_LIBS and its guts have
been moved to QF_PROCESS_NEED_subroutine, with additional modifications to
allow QF_NEED to be used for other targets as well (eg, directories,
executables, etc).
