Change the readelf and objdump programs so that they will automatically follow links to separate debug info files.
* configure.ac (follow-debug-links): Add option to enable or
disable the following of debug links by default. Set the
default for the option to be 'follow'.
* dwarf.c (do_follow_links): Initialise with DEFAULT_FOR_FOLLOW_LINKS.
(dwarf_select_sections_by_names): Add no-follow-links option.
(dwarf_select_sections_by_letter): Add 'N' option.
* objdump.c (usage): Add conditional text describing the
follow links option.
(slurp_symtab): Ensure that there is a NULL entry at the end
of the symbol table.
(slurp_dynamic_symtab): Likewise.
(dump_bfd): When extending the symbol table, ensure that there
is still a NULL entry at the end.
* readelf.c (usage): Add conditional text describing the
follow links option.
* doc/binutils.texi: Update documentation for objcopy and
readelf.
* doc/debug.options.texi: Update documentation of the
follow-links option.
* config.in: Regenerate.
* configure: Regenerate.
* testsuite/binutils-all/compress.exp: Add the -WN option to
objdump command lines that are not expecting to follow links.
* testsuite/binutils-all/readelf.exp: Add the
--debug-dump=no-follow-links option to tests that are not
expecting to follow debug links.
gas * testsuite/gas/mach-o/sections-1.d: Stop automatic debug link
following.
* testsuite/gas/xgate/insns-dwarf2.d: Likewise.
ld * testsuite/ld-elf/sec64k.exp: Stop readelf from automatically
following debug links.
