uninative-tarball: glibc-gconv-{utf-16, cp1252} for binutils windres
The windres binutils binary which is used for Windows resource files
requires utf-16 and cp1252 encoding support in order to correctly
generate resource files with strings. As such when using uninative to
build mingw resources for a nativesdk target the windres binary is
executed on the native host, thus using the uninative libc and gconv
modules.
