Log message:
Use CFLAGS when creating the archive.  This fixes building under IRIX64
using gcc, as we need the ABI specific flags.

Log message:
Garbage collect BUILDLINK_PKGBASE.<pkg> from buildlink3: it is not anymore
used since revision 1.139 of mk/buildlink3/bsd.buildlink3.mk.

Log message:
Fix serious bug where BUILDLINK_PACKAGES wasn't being ordered properly
by moving the inclusion of buildlink3.mk files outside of the protected
region.  This bug would be seen by users that have set PREFER_PKGSRC
or PREFER_NATIVE to non-default values.

BUILDLINK_PACKAGES should be ordered so that for any package in the
list, that package doesn't depend on any packages to the left of it
in the list.  This ordering property is used to check for builtin
packages in the correct order.  The problem was that including a
buildlink3.mk file for <pkg> correctly ensured that <pkg> was removed
from BUILDLINK_PACKAGES and appended to the end.  However, since the
inclusion of any other buildlink3.mk files within that buildlink3.mk
was in a region that was protected against multiple inclusion, those
dependencies weren't also moved to the end of BUILDLINK_PACKAGES.

Log message:
If the ${PKGBASE} of a package doesn't match the token passed to
BUILDLINK_PACKAGES, then set BUILDLINK_PKGBASE.<pkg> explicitly so that
we can map from <pkg> to BUILDLINK_PKGBASE.<pkg>.

Log message:
bdb.buildlink3.mk is used to select a Berkeley DB implementation for
use by pkgsrc.  It will automatically depend on either db, db3, or db4
if the native one isn't sufficient.  The two variables that control its
behaviour are:

BDB_DEFAULT is a user-settable variable whose value is the default
       Berkeley DB implementation to use.

BDB_ACCEPTED is a package-settable list of Berkeley DB implementations
       that may be used by the package.

E.g., if you always want to use DB4 as the Berkeley DB for all of the
packages, then you can just set:

	BDB_DEFAULT=	db4

in your /etc/mk.conf.

Packages that currently include db*/buildlink3.mk should be made to
include bdb.buildlink3.mk instead.

Log message:
If we're passing through MAKEFLAGS variables whose values may contain
spaces, use the :Q modifier instead of double-quoting the value.  This
avoids breakage when executing the just-in-time su targets.

Log message:
Make PREFER_PKGSRC just yes/no or a list of packages.  This makes it
simpler to understand.

Log message:
Rename BUILDLINK_PREFER_PKGSRC to PREFER_PKGSRC so that we can use its
value outside of buildlink-related files.

Log message:
Support a new global variable:

BUILDLINK_PREFER_PKGSRC
	This variable determines whether or not to prefer the pkgsrc
	versions of software that is also present in the base system.

	This variable is multi-state:
		defined, or "yes"	always prefer the pkgsrc versions
		not defined, or "no"	only use the pkgsrc versions if
					needed by dependency requirements

	This can also take a list of packages for which to prefer the
	pkgsrc-installed software.  The package names may be found by
	consulting the value added to BUILDLINK_PACKAGES in the
	buildlink[23].mk files for that package.

Log message:
Support BUILDLINK_DEPENDS.<pkg> being a list of values.
