Any target which dynamic libraries will naturally support something like "default" (meaning that the symbol is visible outside this shared object) and "hidden" (meaning that it isn't) visibilities, but "protected" is really an ELF-specific concept with weird semantics designed around the convenience of dynamic linker implementations.
