buildlink2.mk files back into the main trunk. This provides sufficient
buildlink2 infrastructure to start merging other packages from the
buildlink2 branch that have already been converted to use the buildlink2
framework.
set FOO_CONFIG=${BUILDLINK_CONFIG_WRAPPER.foo} in both CONFIGURE_ENV and
MAKE_ENV. We remove the check for GNU_CONFIGURE because if a package
Makefile includes the buildlink.mk file, then it most likely wants to use
the config script wrappers as well. Change suggested by Hubert Feyrer
(hubertf) and Tomasz Luchowski (zuntum).
BUILDLINK_PREFIX.<pkgname>. This allows buildlink to find X11BASE packages
regardless of whether they were installed before or after xpkgwedge was
installed. Idea by Alistair Crooks <agc@pkgsrc.org>.
FOO_REQD=1.0 being converted to foo>=1.0, one can now directly specify
the dependency pattern as FOO_DEPENDS=foo>=1.0. This allows things like
JPEG_DEPENDS=jpeg-6b, or fancier expressions like for postgresql-lib.
Change existing FOO_REQD definitions in Makefiles to FOO_DEPENDS.
