	* elf32-hppa.c (elf32_hppa_relocate_section): If there was a link
	error of some sort (for example, undefined symbols), then do not
	apply any relocs, just notify the user of the errors.
	(elf32_hppa_backend_begin_write_processing): Do not build a symbol
	extension section for an executable (it's useless).
	(elf32_hppa_link_output_symbol_hook): Do nothing if there was a
	link error of some sort (for example, undefined symbols).
	(elf32_hppa_read_symext_info): Kludge.  Turn off SEC_HAS_CONTENTS
	for all the input symbol extension sections to keep the generic
	BFD code happy.  Temporarily turn it on to read the contents of
	the symbol extension section.
