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.
