Actually, ld.so only handles ELF executables (e.g. programs written in C
or C++). It's the responsibility of the execve() system call in the
kernel to deal with different binary formats, such as scripts beginning
with the magic "#!" characters. Have a look at fs/binfmt_script.c in the
kernel if you're interested.
