Some tests may benefit from using resources from a build directory. This introduces three variables that can help tests find resources in those directories.
First, a BUILD_DIR is assumed to exist, given that the primary form of running the acceptance tests is from a build directory (which may or may not be the same as the source tree, that is, the SOURCE_DIR). If the directory containing the acceptance tests happens to be a link to a directory, it's assumed to it points to the source tree (SOURCE_DIR), which is the behavior defined on the QEMU Makefiles. If the directory containing the acceptance tests is not a link, then a in-tree build is assumed, and the BUILD_DIR and SOURCE_DIR have the same value.
