If tar is deciding that the file has "changed" just because the link
count on the dentry has increased, that sounds like it is probably a bug
in tar and ought to be fixed there.

That said, I can't immediately think why autotools_copy_aclocal couldn't
use a symlink rather than a hard link which would avoid this whole
problem.  If the file is in the sysroot then there should be no risk of
it going away underneath its user.
