When I was refactoring cmd_ar_builtin in scripts/Makefile.build, I noticed the build breakage of s390. Some Makefiles of s390 add extra dependencies to built-in.a; built-in.a depends on timestamp files *.o.chkbss, but $(AR) does not want to include them into built-in.a. Insert a phony target 'chkbss' in between so that $(AR) can take $(filter-out $(PHONY), $^) as input. While I was here, I refactored Makefile.chkbss a little bit.
