If anything it would be TARGET=3Darm, but that's implied by the TARGET_ARCH=3Darmv6. I suspect the problems you're seeing are more fallout from all the recent WITH/WITHOUT build system changes. I've been so focused on doing arm MFCs for the past week I haven't tried to build -current for a few days. Since 10-stable is now in sync [1] with -current for arm stuff, but doesn't have all the recent build system changes, that might be a workable alternative for you for now... just build 10-stable instead of -current. [1] mostly -- I'm still finding a few misc changesets that I missed on the first pass, and build/run testing of 10-stable on arm is just beginning. -- Ian
