+	* 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.
