fix ld-behavior-dependent crash in ppc64 ldso startup

the 32-bit pc-relative address for stage 2 of dynamic linker entry was
wrongly loaded with a zero-extending load instead of sign-extending
load, resulting in an invalid jump if the offset happened to be
negative, which depends on the linker's ordering of text sections.
