An updated version of nlist_elf32.c has been pulled up to the 1.3
release branch, because the older version didn't compile cleanly on
pmaxes.  This affects the Alpha port, since nlist_elf64.c just defines
the ELF word size and then includes the 32-bit version.

The change just placates GCC's flow analysis by initializing two local
variables. I think it's totally innocuous, but it'd be nice if someone
can confirm that it causes no problems for the Alpha.
