I do not understand this.  dist-hook is there to allow modifications
of things inside $(distdir)/.  I believe this directory is never
read-only.

Since this is the inner `make dist', every file in the source tree is
expected to be up-to-date (or the tarball generated by the first `make
dist' is bogus), and their should be no reason to update them.  That
also guaranties that `make dist' can work even of the source tree is
read-only.
