[perl #28170] [PATCH] marginally better negative zero detection
[perl #28170] [PATCH] marginally better negative zero detection

ALl of the big-endian tinderboxes are currently failing t/pmc/perlnum.t
test 36 (the one that tries to handle negative zero).  (The two Solaris
tinderboxes are still running a very old version of parrot that's
irrelevant.)

This patch makes the current non-portable test slightly less non-portable.
