[PATCH] Makefile: Disable gettext in the Git submodule

[Jason A. Donenfeld]

Hi Lukas,

A user on IRC reported that his prior trick of passing NO_ICONV to
make didn't cut it, and that now he had to pass in NO_GETTEXT. It
seems that in the Makefile reworking this commit somehow got
overwritten. Is globally disabling gettext/iconv something we still
want to do Something to consider as well -- we seem to use ICONV in
parsing.c. What's your assessment?

Thanks,
Jason
