Nor can we add a meson.build file to capstone/, because the git submodule would then always report "untracked files". Fixing that would require creating our own branch on the qemu git mirror, at which point we could just as easily create a native meson subproject. Instead, build the library via the main meson.build. This improves the current state of affairs in that we will re-link the qemu executables against a changed libcapstone.a, which we wouldn't do before-hand. In addition, the use of the configuration header file instead of command-line -DEFINES means that we will rebuild the capstone objects with changes to meson.build.
