b8871f357f Properly implement STT_COMMON 
The BFD configure option, --enable-elf-stt-common, can't be to used to
verify STT_COMMON implementation with the normal binutils build.  Instead,
this patch removes it from BFD.  It adds --elf-stt-common=[no|yes] to ELF
assembler/objcopy and adds -z common/-z nocommon to ld.

A configure option, --enable-elf-stt-common, is added to gas to specify
whether ELF assembler should generate common symbols with the STT_COMMON
type by default.

Since BSF_KEEP_G is never used, it is renamed to BSF_ELF_COMMON for ELF
common symbols.

451133cefa gas: section name substitution sequence 
This patch adds the ability to automatically construct a section name
based on the prior section.

When gas is invoked with --sectname-subst, the occurrence of %S in a
section name will be substituted by the name of the current section. For
example:

	.macro exception_code
	.pushsection %S.exception
	[exception code here]
	.popsection
	.endm

	.text
	[code]
	exception_code
	[...]

	.section .init
	[init code]
	exception_code
	[...]

The first and second exception_code invocations create the
.text.exception and the .init.exception sections respectively.  This is
useful e.g. to discriminate between anciliary sections that are tied to
.init code and can be discarded at run time when initialization is over
vs anciliary sections tied to .text sections that need to stay resident.

	* as.c (show_usage): Document --sectname-subst.
	(parse_args): Add --sectname-subst.
	* as.h (flag_sectname_subst): New.
	* config/obj-elf.c (obj_elf_section_name): Add %S substitution.
	* doc/as.texinfo: Document it.

0ce398f106 Add --compress-debug-sections=[none|zlib|zlib-gnu|zlib-gabi] 
This patch adds --compress-debug-sections=[none|zlib|zlib-gnu|zlib-gabi]
to ld for ELF targets to support generating compressed DWARF debug
sections.  We always generate .zdebug_* section since section names have
been finalized and they can't be changed easily when compression is
being performed.

	(_bfd_elf_assign_file_positions_for_relocs): Renamed to ...
	(_bfd_elf_assign_file_positions_for_non_load): This.  Change

	SEC_ELF_COMPRESS is set.
	(_bfd_elf_write_object_contents): Updated.
	(_bfd_elf_set_section_contents): Write section contents to
	the buffer if SEC_ELF_COMPRESS is set.
	* merge.c: Include "elf-bfd.h".
	(sec_merge_emit): Add arguments for contents and offset.  Write
	to contents with offset if contents isn't NULL.
	(_bfd_write_merged_section): Write section contents to the
	buffer if SEC_ELF_COMPRESS is set.  Pass contents and
	output_offset to sec_merge_emit.
	* elflink.c (bfd_elf_final_link): Allocate the buffer for
	output section contents if SEC_ELF_COMPRESS is set.

151411f8af Add SHF_COMPRESSED support to gas and objcopy 
This patch adds --compress-debug-sections={none|zlib|zlib-gnu|zlib-gabi}
options to gas and objcopy for ELF files. They control how DWARF debug
sections are compressed.  --compress-debug-sections=none is equivalent to
--nocompress-debug-sections.  --compress-debug-sections=zlib and
--compress-debug-sections=zlib-gnu are equivalent to
--compress-debug-sections.  --compress-debug-sections=zlib-gabi compresses
DWARF debug sections with SHF_COMPRESSED from the ELF ABI.  No linker
changes are required to support SHF_COMPRESSED.
