On macOS with Homebrew's argp-standalone, Findargp's link test for argp_parse fails with an undefined strchrnul, because libargp.a itself references that GNU extension and the platform has none. The module then stops with "does not have a symbol named argp_parse", which is not what is wrong. Probe for strchrnul first (with _GNU_SOURCE, so glibc answers correctly). Where it exists, the test is unchanged. Where it is missing, run the same argp_parse test with a local definition of strchrnul, and have ptouch-print supply that definition for the real build. On glibc nothing changes: the probe finds strchrnul and the original test runs. Checked on Debian stable in the same session.
