* emulparms/elf64hppa.sh (OTHER_READONLY_SECTIONS): Put stubs before
unwinders so that they are closer to the text section. (OTHER_BSS_SECTIONS): Define. (EXECUTABLE_SYMBOLS): Provide __SYSTEM_ID and _FPU_STATUS. (INIT_START, INIT_END): Define. (FINI_START, FINI_END): Define. * scripttempl/elf.sc: Add support for INIT_START, INIT_END, FINI_START, FINI_END and OTHER_BSS_SECTIONS.
