What I had in mind when I made imake and xmkmf into tools in the tools
USE_TOOLS+=imake means the package uses the tool during "some part of
the build", whether that be the configure stage or the build stage or
whatever. Some packages have GNU configure scripts that (inexplicably)
call imake or xmkmf for some (stupid) reasons known only to the authors.
USE_IMAKE means that the package uses the *.cf files to build Makefiles
in the configure stage that are used in the build and install phases.
These types of packages are "X11" packages that rely on those silly *.cf
files for path information.
USE_IMAKE does imply USE_TOOLS+=imake while the converse is not true.
