strncasecmp does not use strncasecmp_l.  It just calls tolower, which
calls isupper, which in turn calls a function accessing the
__global_locale struct.  I *think* the problem is that this pulls in all
of libc/locale/locale.c, so the problem could perhaps alleviated by
moving __locale_ctype_ptr() and the __global_locale struct to separate
files...?

When I implemented this functionality I asked specificially for input
from users of small targets.  I tried to keep the footprint as small as
possible, but there's very likely room for further improvement.

So, here's my request again:  If somebody has problems with the size
of the code due to the locale stuff, please provide patches.
