I apologize for wasting your time.

The reason "make check" failed is because I somehow thought that SGI had
adopted Arthur Olson's tz data <ftp://elsie.nci.nih.gov/pub/> (see also:
<http://cspry.co.uk/computing/Indy_admin/TIMEZONE.html>).

After installing Olson's tz library and data and
adding '-L/usr/local/lib -ltz' to the list of libraries,
"make check" succeeds.

It would be helpful to sprinkle a few reminders of the existence of
Olson's data in the documentation.
