Being unable to unpack a tarball is much worse that being unable to
run the test suite or clean the build tree, though.  I'm sure some
people won't even know how to proceed in that situation.

I'm reluctant to make changes in the build scripts on the release
branch at this point.  make-dist only affects Emacs maintainers who
prepare the tarball, so having some trouble there is not a
catastrophe.  But a problem in Makefile's will affect everyone who
builds the release.  So I'd prefer to keep those two changes on master
for now.
