an easy fix for strcmpi and we move on

Here in branch paxed-new_lev_comp-B (branched
from paxed-new_lev_comp) is a simple fix
for the strcmpi issue.

The bottom section of lev_main.c has a bunch
of forced linkages to names from NetHack etc.
	#ifdef STRICT_REF_DEF
	bunch of stuff
	#endif

This change to lev_main should make everything
work for those that don't supply a compiler
library version of strcmpi()

With this patch, those people can just
add a -DSTRICT_REF_DEF to their compile line
for lev_main.c.

This would close the issue in a simple way,
and doesn't require linking in anything new to
the level compiler, or modifying any port's Makefiles etc.
