As I already said, the problem is that gcc's alias only works for
symbols which are defined in the same source file as the alias
declaration.

Apple's linker has an option "-alias_list" to read what are essentially
--defsym argument pairs, from a file. That'd be even more helpful, but
building an argument list from the file works well enough.
