Change a mkdir to mkdir -p in the patch to Makefile.in, so that
the include directories get made if they don't exist, as they're put
in a non-standard place.
Add default directories for Perl's Configure script to search on
NetBSD. Now why can't it grab these from the installer's path or
other environment variables?
Modify FreeBSD's ecvt patch, so that it's commented out in FreeBSD,
but still short-circuits in other 4.4-lite derived systems.
Add NetBSD/i386-specific files.
Only tested on NetBSD/i386 (1.2G) so far.
