In principle, that's fine.  The attached runs a test during bootstrap to
decide whether the workaround is necessary.  This simply means that if
the person who bootstraps a release uses a new enough (or suitably  
patched)
autotoolset then the extra copies aren't added to the dist tarball.

No need.  I think this version being self correcting as the installed  
tools
are upgraded is sufficient.

I prefer the attached... ;-)

Tested with stock 1.9.6/2.59, darwin & subdir-libobj patched  
1.9.6/2.5.9, and
bootstrapping with one and `make dist' with the other set in both  
directions.
