* 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.

        * scripttempl/elf.sc: Add support for INIT_START, INIT_END,
        FINI_START, FINI_END and OTHER_BSS_SECTIONS.
