Fix generic linker symbol output when weak is overridden by strong

Yes, I know this also affects bfd_link_hash_indirect, but output of
indirect and warning symbols looks quite broken anyway.

	flag from bfd_link_hash_defined symbols.

Don't create .eh_frame_hdr on shared lib bfd

If no object files have .eh_frame, but some shared library does, then
ld creates a .eh_frame_hdr section using the shared library bfd.  This
is silly since shared library .eh_frame sections don't contribute to
the output .eh_frame and thus no .eh_frame_hdr is needed.

Also, the bfd section list and count is cleared for shared libraries,
and a zero section count used as a flag in lang_check to omit a call
to bfd_merge_private_bfd_data for shared libraries.  If we create a
section on a shared lib bfd then ld will wrongly attempt to merge the
shared library private bfd data.

	PR 17742
	* ld/emultempl/elf32.em (gld${EMULATION_NAME}_after_open): Exclude
	shared libraries in loop looking for .eh_frame sections.
	Similarly for build-id loop.

	PR binutils/17671
	* objcopy.c (copy_main, strip_main): Add D and U to the list of
	accepted short versions of long options.
AVR: Assembler now prepares for linker relaxation by default.

Have the assembler prepare for linker relaxation by default.  This
means that users will be able to make use of linker relaxation without
having to adjust the assembler flags, this can make life easier when
compiling libraries.

Having this on by default in the assembler should make no difference to
the assembler code produced, however, some of the debug information will
be slightly less compressed.

A few tests needed to be updated as a result of this change as they
relied on linker relaxation support being off by default.

I've tightened up the definition of which sections can be relaxed on AVR
as part of this commit, the assembler used to think that all
non-debugging sections could be relaxed, when in reality only code
sections can be relaxed for AVR.  The previous definition was not
dangerous, just over cautious.  The new tighter definition allows an
extra test (gas/testsuite/gas/all/forward.d) to continue to pass.

gas/ChangeLog:

	* config/tc-avr.c (struct avr_opt_s): Change link_relax to
	no_link_relax, extend comment.
	(enum options): Add new OPTION_NO_LINK_RELAX.
	(md_longopts): Add entry for -mno-link-relax.
	(md_parse_option): Handle OPTION_NO_LINK_RELAX, and update
	OPTION_LINK_RELAX.
	(md_begin): Initialise linkrelax from no_link_relax.
	(md_show_usage): Include -mno-link-relax option.
	(relaxable_section): Only allocatable code sections can be
	relaxed.
	* config/tc-avr.h (TC_LINKRELAX_FIXUP): Define.

gas/testsuite/ChangeLog:

	* gas/all/gas.exp: Test will not pass on AVR due to linker
	relaxation support.
	* gas/avr/noreloc_withoutrelax.d: Add -mno-link-relax option.
	* gas/avr/link-relax-elf-flag-clear.d: Likewise.

ld/testsuite/ChangeLog:
