[src/trunk]: src/sys/arch/sgimips/sgimips When loadfile() leaves the ELF head...

branches:  trunk
changeset: 517562:a994b42e59ad
user:      mhitch <mhitch%NetBSD.org@localhost>

description:
When loadfile() leaves the ELF header at the end of the kernel, it enables
erroneous code that tries to compute the end of the symbol table.  Disable
that for now so that kernels don't hang when booted from the disk.
