When building kselftest in a separate output directory: /tmp/cc44s4yX.o: In function `socket_send_fd': tools/testing/selftests/android/ion/ionutils.c:221: undefined reference to `sendtosocket' /tmp/cc44s4yX.o: In function `socket_receive_fd': tools/testing/selftests/android/ion/ionutils.c:243: undefined reference to `receivefromsocket' The dependencies for the various test programs are expressed twice: 1. Once using $(TEST_GEN_FILES), which supports building in the source directory only, 2. A second time using $(OUTPUT), which supports building in either the source or build directory, but lacks a dependency of ionmap_test on ipcsocket, causing the link error above. Fix this by: - Adding the missing dependency to 2, - Dropping superfluous rule 1. Remove the "all" target while at it, as that is already handled by the included lib.mk.
