Apparently this is indirectly via devel/lutok = being used. As for one of the example make.conf's that I'm using that results in the = behavior: (it does target -march=3Darmv7-a -mcpu=3Dcortex-a7 very explicitly) > # more /etc/make.conf > DEFAULT_VERSIONS+=3Dperl5=3D5.22 > WRKDIRPREFIX=3D/usr/obj/portswork > WITH_DEBUG=3D > WITH_DEBUG_FILES=3D > MALLOC_PRODUCTION=3D > # > TO_TYPE=3Darmv6 > VERSION_CONTEXT=3D11.0 > CFLAGS+=3D-target ${TO_TYPE}--freebsd${VERSION_CONTEXT}-gnueabi = -march=3Darmv7-a -mcpu=3Dcortex-a7 -mfloat-abi=3Dsoftfp = -mno-unaligned-access Note: the projects/clang380-import -r295601 buildworld/buildkernel = context installed on the rpi2 also has those CFLAGS entries.
