I have added the support for BIG5 encoding into libc/libxpg4/mklocale.

the diff is attached below. This is done on the 3.0 source-tree.
I have test this on 2.2-stable before, but I don't have a 3.0 machine
right now.

This patch is mainly to make libc support BIG5 encoding, thus add
zh_TW.BIG5 locale to 3.0.
