install.texi (hppa): Update links for HP-UX patches.

	* doc/install.texi (hppa): Update links for HP-UX patches.  Revise
	notes on linker selection and configuration for 64-bit HP-UX port.
	* doc/invoke.texi (hppa): Remove hppa text from description for
	-ffunction-sections and -fdata-sections.  Document -static, -nolibdld
	and -threads options.
	* pa-hpux10.h (LIB_SPEC): Add link options to resolve dependency of
	libc.a on libdld.sl when -static is specified and -nolibdld is not
	specified.
	* pa64-hpux.h (LIB_SPEC): Likewise.
	* pa-hpux11.h (LIB_SPEC): Likewise.
	(LINK_SPEC): Add __gcc_plt_call as an undefined symbol when -shared
	is not specified.
