[uClibc] TZ environment values for glibc timezones

I'm in the process of  converting an existing embedded application from 
being glibc-based to uclibc-based, and was hoping for some help with 
dealing with the mapping of the TZ environment variable.  Specifically, 
I fully understand the encoding difference (i.e. using the POSIX based 
encloding rule in the TZ variable for daylight savings time encoding and 
the like), but what I don't particularly look forward to is the 
laborious and error prone process of producing the mapping from a couple 
hundred file-name based timezone idenfitiers (i.e. America/Chicago, 
Asia/Tehran, etc, etc) to the correct POSIX TZ encoding.  Has anyone 
using uclibc already done this mapping, produced a tool to crawl the 
glibc zoneinfo and generate this mapping, or any other solution?

I've done some searching on the archives and the web in general, but 
haven't found an anwer to this, so I hope someone here can help.
