Subject: [PATCH] perl.h: Need just MULTIPLICITY for context

PERL_UNUSED_CONTEXT should be defined properly whenever there is a
my_perl.  This happens whenever MULTIPLICITY is defined.  Prior to this
commit PERL_UNUSED_CONTEXT got defined properly only when threads are
being used.  You can have MULTIPLICITY without threads.
