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 BLD_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 SRC_DIR).
If the directory containing the acceptance tests happens to be a link
to a directory (kept as LNK_DIR), it's assumed to it points to the
source tree (SRC_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 BLD_DIR and SRC_DIR are
the same and LNK_DIR is set None.
