Indeed, the -z undefs option was only introduced in binutils 2.30, so any toolchain using a binutils older than that is not able to use -z undefs. So I'd say that Fabrice's proposal is fine. Another option would be to detect if the toolchain support -z undefs, and only use --no-undefined if -z undefs is supported, for example.
