poke-1.0 on Linux/sparc64

[Bruno Haible]

On a Linux/sparc64 machine (gcc202.fsffrance.org), the build of
poke-1.0 works fine, and passes nearly all tests:

$ make check
...
Running /home/haible/poke-1.0/testsuite/poke.time/time.exp ...
FAIL: poke.time/time32.pk output pattern test

                === poke Summary ===

# of expected passes            5151
# of unexpected failures        1
# of unsupported tests          7


More details are found in the poke.log file:
=========================================================
PASS: poke.time/time32.pk execution test

#<2019-Dec-12 8:54:56>
#<1972-Feb-29 1:2:3>

As you can see, two out of the three dates are off by more than one year.
