I don't know what Solaris does exactly in -z defs about the interpreter, but
at least on glibc systems it would IMHO make sense to allow satisfying
symbols for -z defs with symbols from dynamic linker as glibc relies on
this behaviour (otherwise one has to use -z defs only with explicit
/lib/ld-*.so on the command line).
