742caba5 - Remove support for OS/2 (based on EMX directly).

Remove support for OS/2 (based on EMX directly). Nowadays, KO Myung-Hun <komh78@gmail.com> uses an approach based on kLIBC instead of emx+gcc. This kLIBC (https://github.com/bitwiseworks/libc) contains iconv already. * os2: Remove directory.
