+Subject: [PATCH] build: use -fcf-protection=none when available
+
+Some hardened gcc v9 compilers (such as the one in Ubuntu)
+default this option which for seabios leads to emulation errors
+when running in KVM (does not trigger in TCG) on older intel
+chips of the Penryn generation (~2006-2008).
+
+Symptom in KVM looks like:
+ KVM internal error. Suberror: 1
+ emulation failure
