Selftest for memfd shows build error as below:
```
gcc -D_FILE_OFFSET_BITS=64 -I../../../../include/uapi/ -I../../../../include/ -I../../../../usr/include/    fuse_mnt.c  -o /home/sjpark/linux/tools/testing/selftests/memfd/fuse_mnt
/tmp/cc6NHdwJ.o: In function `main':
fuse_mnt.c:(.text+0x249): undefined reference to `fuse_main_real'
collect2: error: ld returned 1 exit status
```

The build fails because output file is specified without $(OUTPUT) and
LDFLAGS is used though Makefile implicit rule is used.  This commit
fixes the error by specifying output file path with $(OUTPUT) and using
LDLIBS instead of LDFLAGS.

In order to remove the duplicated targets, introduce TEST_GEN_PROGS, TEST_GEN_PROGS_EXTENDED, TEST_GEN_FILES to indicate the compiled objects.

selftests: Introduce minimal shared logic for running tests 2015-03-13T21:13:40+00:00 Michael Ellerman mpe@ellerman.id.au 2015-03-11T04:05:59+00:00 5e29a9105b1a0da86eff0ad6ae015997b49d4d1d This adds a Make include file which most selftests can then include to get the run_tests logic. On its own this has the advantage of some reduction in repetition, and also means the pass/fail message is defined in fewer places. However the key advantage is it will allow us to implement install very simply in a subsequent patch. The default implementation just executes each program in $(TEST_PROGS). We use a variable to hold the default implementation of $(RUN_TESTS) because that gives us a clean way to override it if necessary, ie. using override. The mount, memory-hotplug and mqueue tests use that to provide a different implementation. Tests are not run via /bin/bash, so if they are scripts they must be executable, we add a+x to several.
