bug#32423: 27.0.50; Compilation fails when sh points to zsh

[Tino Calancha]

I started to suffer this recently (~ since this month).
When
bin/sh points to /bin/zsh

I get an zsh parse error as follows:

make[2]: Entering directory '/home/calancha/soft/emacs-master/admin/grammars'
make[2]: Nothing to be done for 'all'.
make[2]: Leaving directory '/home/calancha/soft/emacs-master/admin/grammars'
zsh:8: parse error near `done'
