[tlbuild] Patches for building TeXlive with CYGWIN-gcc-3.4.4

[Rodrigo Medina]

Thanks Vladimir for you reply in
http://tug.org/pipermail/tlbuild/2008q4/000445.html

I assume that it is also correct that xdvi should link dynamically
to the system iconv; so is, perhaps, the fact that info links
dynamically to the system ncurses instead than statically to the
provided ncurses, the only bug?

Best regards
