selftests: set the BUILD variable to absolute path
commit 5ad51ab6 upstream. The build of kselftests fails if relative path is specified through KBUILD_OUTPUT or O=<path> method. BUILD variable is used to determine the path of the output objects. When make is run from other directories with relative paths, the exact path of the build objects is ambiguous and build fails. make[1]: Entering directory '/home/usama/repos/kernel/linux_mainline2/tools/testing/selftests/alsa' gcc mixer-test.c -L/usr/lib/x86_64-linux-gnu -lasound -o build/kselftest/alsa/mixer-test /usr/bin/ld: cannot open output file build/kselftest/alsa/mixer-test Set the BUILD variable to the absolute path of the output directory. Make the logic readable and easy to follow. Use spaces instead of tabs for indentation as if with tab indentation is considered recipe in make.
