Christian Ehrhardt 9584d3d00a build: disable fcf-protection on -march=486 -m16 ... Some of the roms build with -march=i486 -m16 which is incompatible with -fcf-protection. That in turn is can be set by default, for example in Ubuntu [1]. That causes: cc1: error: ‘-fcf-protection’ is not compatible with this target This won't work on -march=i486 -m16 and no matter if set or not we can override it to "none" if the option is known to the compiler to be able to build reliably.
