In an automated build system, where valgrind and ffmpeg get updated in parallel, a race condition may occur in which valgrind/valgrind.h is available when configure runs but not if libavutil/log.c gets compiled.
Using CONFIG_VALGRIND_BACKTRACE helps to avoid this problem, because it allows to prevent the inclusion of the autodetected valgrind.h by using a configure switch.
