For historical reasons, rcutorture places its build products in a tools/testing/selftests/rcutorture/b1 directory using the O= kbuild command-line argument. However, doing this requires that the source directory be pristine: Not just "make clean" pristine, but instead "make mrproper" (or, equivalently, "make distclean") pristine. Therefore, rcutorture executes a "make mrproper" before each build. Unfortunately, "make mrproper" has the side effect of removing pretty much everything, including tags files and cscope databases, which can be inconvenient to people whose workflow centers around a single source tree. This commit therefore makes rcutorture do the build directly in the source directory, removing the need for "make mrproper". This works because all needed build products are moved to their proper place in the "res" directory immediately after the build completes, so that multiple rcutorture kernels can still run concurrently.
