.. they're needed for the RPC generation in glibc
on both Cygwin and MinGW-w64.
Neither are built on GNU/Linux and iconv is not
built on Darwin.
Two patches for gettext are needed, one so that
-O0 works and one so that static builds can be
made.
They can take a good while to build, so if not
needed for_host or for_build then they are not
built.
