the host I use to cross compile is running 10.1,
/usr/bin/cc
but I also tried CC=3Dclang
there is another error, which appeared before, and I solve it by setting =
MK_FORMAT_EXTENSIONS=3Dno
(which out it complains =E2=80=A6 malformed conditional =
(${MK_FORMAT_EXTENSIONS) =3D=3D =E2=80=9Cno=E2=80=9D)
