Makefile fixes / JUTNameTab (#129)

* Makefile: Fix issues with iconv causing it to break under devkitPro / msys

The version of iconv included in devkitPro does not have a -o option,
so replace it with normal shell redirection. Also, SHIFT-JIS does not
have a mapping for ~, so output the Windows CP932 variant instead,
which does. See:
https://en.wikipedia.org/wiki/Tilde#Unicode_and_Shift_JIS_encoding_of_wave_dash
https://en.wikipedia.org/wiki/Code_page_932_(Microsoft_Windows)#Single-byte_character_differences

* Update diff configuration

-Bbinary doesn't seem to work with my copy of
bjdump (it says it can't decode unknown architecture)

Cheese things by using expected/ instead of having
the user place things manually.

* JUTNameTab

* J3DPacket / J3DDrawBuffer

* format
