SYMLINKS creates symlinks in the DESTDIR, not the .OBJDIR.

LNFILES is provided for source paths that you need in the .OBJDIR
that either  need a different name than that in the dist/ .PATH, or
have to be in the current directory due to implementation issues with
a host tool.  These (temporary) links are also cleaned when necessary,
unlike $SYMLINKS targets.

We already have a bunch of code in the tree that reinvents the wheel
to enable a build, and will need this more for another reachover build
I'm working on.  This stuff can be simplified with LNFILES now.
