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

Nothing depends on archdep.h pulling in other #includes anymore, so delete the #includes and hide the RELOC_* functions that are only used by lib/csu behind "#ifdef RCRT0"

ld.so boot cleanup support: - put functions and data which are only used before calling the executable's start function into their own page-aligned segments for unmapping (only done on amd64, arm64, armv7, powerpc, and sparc64 so far) - pass .init_array and .preinit_array functions an addition argument which is a callback to get a structure which includes a function that frees the boot text and data - sometimes delay doing RELRO processing: for a shared-object marked DF_1_INITFIRST do it after the object's .init_array, for the executable do it after the .preinit_array - improve test-ld.so to link against libpthread and trigger its initialization late libc changes to use this will come later
