Most (many?) of the tests aren't shell scripts, so that doesn't work, eg:

  $ make -C tools/testing/selftests/ TARGETS=kcmp run_tests
  ...
  make[1]: Entering directory '/home/michael/linus/tools/testing/selftests/kcmp'
  ./kcmp_test: 1: ./kcmp_test: ELF.\x01.\x02.\x010.@�.\x02@@.\x19.@@.@.�.�.\x04.\x02.\x02.\x11.\x01.\x10.\x04.\x04.\x01.\x06����.\x10��.\x10�.�.\x01.\x06.�.�.\x10.�.\x10�.�.\x04.\x02.\x02.\x14.\x10DD.Q�td.\x10R�td.����.\x10��.\x03./lib64/ld64.so.2.\x10.GNU.\x02.\x14.GNUC{: not found
  ./kcmp_test: 13: ./kcmp_test: Syntax error: Unterminated quoted string
  selftests:  kcmp_test [FAIL]


Also some of the ones which are shell scripts require bash, and /bin/sh
may not be bash, eg:

  $ make -C tools/testing/selftests/ TARGETS=cpu-hotplug run_tests
  ...
  make[1]: Entering directory '/home/michael/linus/tools/testing/selftests/cpu-hotplug'
  ./cpu-on-off-test.sh: 9: [: !=: unexpected operator


cheers
