2a9fa50cd8 Add support for ELF shared libraries.
* ld.h (ld_config_type): Add field dynamic_link.
	* ldmain.c (main): Initialize config.dynamic_link to false.  Warn
	on attempts to use -r with -relax, -call_shared or -s.
	* lexsup.c (longopts): Separate OPTION_CALL_SHARED from
	OPTION_NON_SHARED.  Add OPTION_IGNORE.  Adjust macro values
	accordingly.  Add "dy" and "non_shared" options.  Change "Qy" to
	OPTION_IGNORE for now.  Handle OPTION_CALL_SHARED and
	OPTION_NON_SHARED by setting dynamic_link field accordingly.
	Handle OPTION_IGNORE by ignoring it.  Clear dynamic_link field for
	-r and -Ur.
	* ldfile.c (ldfile_open_file): If config.dynamic_link is true, try
	opening a file with a .so extension first.
	* emultempl/elf32.em: New file.
	* emulparams/elf32_sparc.sh (TEXT_START_ADDR): Change to 0x10000.
	(NONPAGED_TEXT_START_ADDR): Likewise.
	(TEMPLATE_NAME): Define as elf32.
	(DATA_PLT): Define.
	* emulparams/elf_i386.sh (TEMPLATE_NAME): Define as elf32.
	* scripttempl/elf.sc: Add placement for new dynamic sections.
	Don't use CREATE_OBJECT_SYMBOLS.  Define _etext, _edata and _end
	outside of any section.  Don't use ALIGN(8); just let one section
	VMA follow another.  Put .dynbss in .bss.  Don't mention debugging
	sections; they'll be handled correctly anyhow.
	* Makefile.in (eelf_i386.c): Depend upon elf32.em, not generic.em.

* mpw-config.in: New file, MPW configuration fragment.
	* mpw-build.in: New file, MPW build script fragment.
	* mpw-make.in: New file, MPW makefile fragment.
	(This file is semi-automatically generated from Makefile.in.)
	* ldfile.c (slash): If MPW, set to `:'.
	* ldlex.l (TRUE_FALSE_ALREADY_DEFINED): If MPW, set this to
	prevent redefinition errors.

fcf276c495 Made many changes to eliminate gcc warnings. Made various
cosmetic changes, declared various things in header files, removed
	various extern declarations from .c files.  No substantive
	changes.
