After this change the generated files are placed in a separate tree (such thet they don't show in the `git status' output anymore) and the dependencies are followed properly (if a .h file changes the appropriate .o files and apps get rebuilt). Tested as follows: > $ make clean > $ make # build succeeds > $ git status # shows clean directory > $ RUNTESTS=1 make # (captured test output matches that of the test run before any changes) > $ touch ./vboot_firmware/include/tlcl.h > $ make # make succeeds > $ find build -type f -newer ./vboot_firmware/include/tlcl.h build/vboot_firmware/lib/rollback_index.o build/vboot_firmware/lib/rollback_index.o.d build/vboot_firmware/a.out build/vboot_fw.a build/utility/vbutil_key build/utility/kernel_utility.d build/utility/vbutil_key.d build/utility/verify_data build/utility/load_kernel_test.d build/utility/vbutil_keyblock.d build/utility/vbutil_kernel build/utility/vbutil_kernel.d build/utility/firmware_utility build/utility/signature_digest_utility.d build/utility/kernel_utility build/utility/verify_data.d build/utility/vbutil_keyblock build/utility/signature_digest_utility build/utility/load_kernel_test build/utility/firmware_utility.d build/tests/vboot_common3_tests build/tests/vboot_common2_tests build/host/a.out $ > Review URL: http://codereview.chromium.org/2845001
