# The tests are compiled and linked using musl-cross. The advantage of this is
# that everything is self-contained and thus easy to reproduce. Musl is also
# designed for static linking with little overhead, which gives us a good
# metric for the "complete package" of a statically linked minimal XML reader
# for each lib.
