    skip fixinc on vxworks7*, amend mkheaders
    
    vxworks7 headers haven't required fixes, and we've decided to avoid
    running fixinc on them.
    
    The problem with that is that, with a dummy fixinc, mkheaders wipes
    out include-fixed but then multi_dir subdirs are not created again, so
    we end up with a limits.h named after each multi_dir, when there are
    non-default multilibs.  Oops.
    
    This patch arranges for a dummy fixinc to be created for *-*-vxworks7*
    targets, and fixes mkheaders so as to create multi_dir subdirs in
    include-fixed after wiping them out, and to copy limits.h so that it
    won't take the name that should be of a subdir (unless the multi_dir
    is limits.h, but that's hopefully never the case ;-)
    
    
    for  fixincludes/ChangeLog
    
            * mkheaders.in: Re-create subdirs, copy limits.h into subdir.
            * mkfixinc.sh: Create dummy fixinc for *-*-vxworks7*.
