mach-o: add page_size to backend data.
This is preliminary work to layout executables.
bfd/
* mach-o.h (bfd_mach_o_backend_data): Add page_size field.
* mach-o-target.c: Check TARGET_PAGESIZE is defined.
(TARGET_NAME_BACKEND): Add TARGET_PAGESIZE.
* mach-o.c (TARGET_PAGESIZE): Define and undefined for
each targets declared.
* mach-o-x86-64.c (TARGET_PAGESIZE): Define.
* mach-o-i386.c (TARGET_PAGESIZE): Define.
