Re: z/OS, iconv, and charset aliases

Thanks. From this, I think we can equate the following vendor names with
GNU canonical names:

Fortunately, all encodings listed as locale encodings in
"Table 3. Supported language-territory names and LT codes for ASCII locales"
of 
https://www.ibm.com/support/knowledgecenter/SSLTBW_2.4.0/com.ibm.zos.v2r4.cbcpx01/locnamc.htm
are in this list.

Omitting identical names on both sides (e.g. BIG5 BIG5), I arrive at the two
attached patches.
