'Do not apply transform to symbolic link targets' [1] Which I
got from googling 'gnu tar transform' IIRC. It is also a
gnuism, but I do not see a portable transform type option as
tar on macOS uses -s and some BSDs seem to lack even that.

I don't think we need a bunch of runners testing devel/make-tarball,
one should be sufficient.

no, but it's called in devel/release before any repo changes
are made.
