'make clean', or a 'git clean -dfx' will delete the PM stamp file, so it cannot be a direct target in such clean conditions, resulting in an error. Normally the PM.stamp is recreated by the git/Makefile, except when a dry-run is requested, for example, as used in the msysgit msvc-build script which implements the compat/vcbuild/README using contrib/buildsystems. The script msvc-build is introduced later in this series. Protect the PM.stamp target when the PM.stamp file does not exist, allowing a Git 'Makefile -n' to succeed on a clean repo. Signed-off-by: Philip Oakley <philipoakley@iee.org> --- This is development of the original "[PATCH 4/17] Makefile: a dry-run can error out if no perl. Document the issue" 2015-06-25, (http://marc.info/?l=git&m=143519054716960&w=2), which simply documented the issue and then used NO_PERL to avoid the problem. See follow on email thread for some discussion.
