QEMU includes GPL "v2 only" code which is not compatible with GPLv3. This means the resulting binaries may not be redistributable! Disable Archipelago (libxseg) by default to prevent accidental license violations. Also warn if linking against libxseg is enabled to remind the user. Note that this commit does not constitute any advice about software licensing. If you have doubts you should consult a lawyer.
