Since the introduction of automatic immutable from the kernel, the munmap() of ld.so boot.text region is now (silently) failing because the region is contained within the text LOAD, which is immutable. So create a new btext LOAD with flags PF_X|PF_R|PF_OPENBSD_MUTABLE, and place all boot.text objects in there. This LOAD must also be page-aligned so it doesn't skip unmapping some of the object region, previously it was hilariously unaligned. ok kettenis and guenther seemed to like it also This one is for powerpc64 and a modified version of the diff deraadt@ mailed out to make sure the LOADs are in increasing address order. this is the i386 version

For more archs, ld.so itself only needs/uses the arch's "just add load offset" 'relative' relocation. Take advantage of that to simplify ld.so's self-reloc code: * give the exceptional archs (hppa and mips64) copies of the current boot.c as boot_md.c * teach the Makefile to use boot_md.c when present * reduce boot.c down to the minimum necessary to handle just relative reloc * teach the Makefile to fail if the built ld.so has other types of relocs

Support for i386 ELF. Not an indication that the change is going to be made, just so that these files are maintained in the tree.
