ld.so: Replace (&bootstrap_map) with BOOTSTRAP_MAP
(&_dl_main_map) is used instead of (&bootstrap_map) to bootstrap static PIE. Define BOOTSTRAP_MAP with (&_dl_main_map) to avoid hardcode to (&bootstrap_map). * elf/rtld.c (BOOTSTRAP_MAP): New. (RESOLVE_MAP): Replace (&bootstrap_map) with BOOTSTRAP_MAP. * sysdeps/hppa/dl-machine.h (ELF_MACHINE_BEFORE_RTLD_RELOC): Likewise. * sysdeps/ia64/dl-machine.h (ELF_MACHINE_BEFORE_RTLD_RELOC): Likewise. * sysdeps/mips/dl-machine.h (ELF_MACHINE_BEFORE_RTLD_RELOC): Likewise.
