I noticed after upgrading my machine that the QEMU is no longer building due to GCC enabling `-fcf-protection` by default, even for targets that don't support it. The included patch came from the QEMU development list, but hasn't be included in any patch releases at the time of writing. https://lore.kernel.org/all/20220208211937.79580-1-vineetg@rivosinc.com/ Until QEMU patches, lets fix it on our end by patching before we build.
