Did you remember to add explicit_bzero.o to LIBOBJS in
the configured Makefile.global?
If it still doesn't work, then evidently your toolchain is selecting
the system's built-in definition of explicit_bzero over the one in
src/port/. This is not terribly surprising given that there has to be
some amount of compiler magic involved in that function. You may have
to resort to actually building Postgres on a platform without
explicit_bzero.
