MKCITRUS=no was set, but I don't think it's usable without
a Makefile patch, so it's built-in.
Check out this bit from the libc Makefile[0]:
--
workaround for I18N stuffs: build singlebyte setlocale() for libc.a,
# multibyte for libc.so. the quirk should be removed when we support
# dlopen() from within statically linked binaries.
CSHLIBFLAGS+= -D_I18N_DYNAMIC"

Could be related to other locale problems I mentioned in a
current-users@
thread[1].
So, I guess it's not related to s-nail.
