As I said I was testing different shells, it was by chance that /bin/sh and
/bin/posh were
linked when I started the build. I also tested dash, ksh, mksh, zsh and of
course bash by
linking them to /bin/sh in turn. The only time the zsh build failed was
when /bin/sh and
/bin/posh were linked.

The common thing I saw, between this output and the output of make from
2002 was the file name "stamp-modobjs". Coincidence? So my next step
was to link sh to bash and verify that would allow the build to complete.
It did.

Sequence for each build of zsh-5.4.2-146-gc8e2f3c3d:

git reset --hard HEAD
git clean -f -d -x >/dev/null
Util/preconfig
configure <with and without options - no difference>
make

By the way, if there is a better way of preparing and doing builds, I'm
open to suggestions. Also building on a newly created branch.

Shell versions tested:

posh:  0.12.6
mksh: @(#)MIRBSD KSH R56 2017/08/24
dash: 0.5.9.1-r3
ksh: Version ABIJM 93v- 2014-12-24
bash: 4.4.12(1)-release
zsh: 5.3.1

Hope this was the info you needed. If you need more info, let me know.
