Use custom linker script for building ECOFF kernel images. The PROM loader 

is fussy about the order of sections and location of memory gaps so we
must produce a firmware friendly version of the kernel as netbsd.ecoff for
network booting

The ELF version uses the standard mips linker script which can be loaded
by the new bootstrap routines
