Makefile.mk: Add a common link_stage function and use it

A few differences with the original link targets:
- 'libs' is now supported on all arch even though only x86 uses it
- compiler_rt is included on arch that previously did not (arm). This
  however has no impact as there compiler_rt is not defined for those
  arch in xcompile
- LIBGCC_FILE_NAME_bootblock is not included, but this was not defined
  anywhere so this is a noop
