Subject: 	* target.h (class Target): Add osabi_ field. 
 (Target::osabi): New function. 	(Target::set_osabi): New function. 
 (Target::Target): Initialize osabi_. 	(Target::do_adjust_elf_header): Make
 pure virtual. 	(Sized_target::do_adjust_elf_header): Declare. 	* target.cc
 (Sized_target::do_adjust_elf_header): New function. 	(class Sized_target):
 Instantiate all versions. 	* freebsd.h (class Target_freebsd): Remove. 
 (Target_selector_freebsd::do_recognize): Call set_osabi on 	Target. 
 (Target_selector_freebsd::do_recognize_by_name): Likewise. 
 (Target_selector_freebsd::set_osabi): Remove. 	* i386.cc (class Target_i386):
 Inherit from Sized_target rather 	than Target_freebsd. 	* x86_64.cc
 (class Target_x86_64): Likewise.
