Current behaviour

In the course of the "Caching..." step of a depends build, the touch command for creating determinstic package archive timestamps fails on OpenBSD. The reason is that the used option -h option (introduced in PR #21995, commit 6ebe576) doesn't exist in OpenBSD's version of touch (see https://man.openbsd.org/touch.1). E.g. for zeromq:

[ ... ]
Postprocessing zeromq...
Caching zeromq...
touch: unknown option -- h
usage: touch [-acm] [-d ccyy-mm-ddTHH:MM:SS[.frac][Z]] [-r file]
             [-t [[cc]yy]mmddHHMM[.SS]] file ...

Expected behaviour

Ideally, creating deterministic package archive timestamps should also work on OpenBSD. As an alternative, if that's not easily possible, the touch command shouldn't be executed at all on OpenBSD, do avoid the "unknown option" error message.

Steps to reproduce

Make a fresh depends build on OpenBSD, e.g. (for zeromq):

$ gmake -C depends clean
$ gmake -C depends NO_BDB=1 NO_BOOST=1 NO_LIBEVENT=1 NO_QT=1 NO_SQLITE=1 NO_NATPMP=1 NO_UPNP=1 NO_USDT=1
