itools, intltool, diff3, sdiff, msgmerge
* Adding USE_TOOLS+=itools to a package Makefile will cause the
tool-directory versions of imake, makedepend, mkdirhier and xmkmf
to point to the ones from the devel/nbitools package.
This change will remove the need for nbitools/buildlink3.mk, which
currently does a bit of hackery to force the "right" imake tools to
be used by packages that need it.
* Adding USE_TOOLS+=intltool to a package Makefile will cause the
local versions of intltool-* inside ${WRKSRC} to be replaced by
copies from the textproc/intltool package. If "intltool" is not
specified as a tool, then we create "broken" intltool-* tools in
the tools directory to help highlight hidden dependencies on the
intltool package.
In addition, modify the tools framework so that if "perl" is not
specified as a tool, then we create a "broken" perl tool in the
tools directory for the same reason as for "intltool".
These two changes together will remove the need for
intltools/buildlink3.mk and should also catch all cases where the
sources' intltools may have been silently used because perl was
found on the system.
* Adding USE_TOOLS+=diff3, USE_TOOLS+=sdiff, or USE_TOOLS+=msgmerge
to a package Makefile will cause the corresponding tool to be pulled
into the tools directory.
These are convenience tools to help simplify dependencies for some
packages.
