lib/locale.t: 3 test failures on FreeBSD

I'm raising this on list rather than filing an RT because this is the 
first time I've attempted to build and test blead on FreeBSD, which I 
have installed in a VirtualBox VM on Linux 16.04 LTS.  The failures may 
reflect my lack of knowledge about this environment rather than Perl 
failures.  In any event, here they are:

$ ack '^not ok' locale_failures.typescript | ack -v TODO
not ok 417 Verify that \0 sorts before any other control
not ok 419 Verify that strings with embedded NUL collate
not ok 420 Verify that strings with embedded NUL and extra trailing NUL 
collate

perl -V output attached.  Suggestions?

Thank you very much.
