Add a test which checks autoloading modules from the host's /stand/arch/vers/kmods works in rump (and that the result is usable ;). On i386 this "just works". For amd64, due to -mcmodel=kernel, things are a little more complicated. We must have the entire rump kernel loaded in the lower 2GB. Currently, this can be done either by using the non-PIC version for the rump kernel compiled with -mcmodel=small, or, as njoly pointed out, using netbsd32, which causes vm_default_addr() to give something in the lower 2GB and therefore shared libs "magically" getting loaded there. I guess it would be possible to put a suggested vaddr into the rump kernel libs and make ld.elf_so map memory from the suggested address if present ... but that's another show. Also thanks to tron for access to an amd64 so that I could verify the test works.
