If all architectures would finally get a vdso implementation you could just add the necessary stub in the vdso, add a symbol in the symbol table of the vdso, and use in the userlevel code
sym = dlsym (RTLD_DEFAULT, "the_symbol_name")
If the returned value is not NULL the symbol exists.
I've described this many times as one of the huge advantages of vdsos, hopefully this time it clicks.
