Your situation is somewhat odd.  You have a working iconv but no way
to get a list of available character sets.  This ought to be a rare
setup.

In this case I chose to make gdb fall back on a fairly large built-in
list.  If you try pick a charset which your iconv cannot handle, gdb
should give an error.

I think the current result is as good as any other.
