	* arm.cc (Target_arm::may_need_copy_reloc): Check for THUMB function
	symbol and call Symbol::may_need_copy_reloc to determine if
	a copy reloc is needed.
	* copy-relocs.cc (Copy_relocs::need_copy_reloc): Return false if -z
	nocopyreloc is given in command line.
	(Copy_relocs::emit_copy_reloc): Assert that -z nocopyreloc is not
	given in command line.
	* i386.cc (Target_i386::may_need_copy_reloc): Remove.
	(Target_i386::Scan::global): Use Symbol::may_need_copy_reloc instead
	of the removed Target_i386::may_need_copy_reloc.
	* options.h (copyreloc): New option with default value false.
	* powerpc.cc (Target_powerpc::may_need_copy_reloc): Remove.
	(Target_powerpc::Scan::global): Use Symbol::may_need_copy_reloc
	instead of the removed Target_powerpc::may_need_copy_reloc.
	* sparc.cc (Target_powerpc::may_need_copy_reloc): Remove.
	(Target_sparc::Scan::global): Use Symbol::may_need_copy_reloc
	instead of the removed Target_sparc::may_need_copy_reloc.
	* symtab.h (Symbol::may_need_copy_reloc): New method definition.
	* x86_64.cc (Target_powerpc::may_need_copy_reloc): Remove.
