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.
