MFV: Only emit movw on ARMv6T2
Building for the FreeBSD default target ARMv6 was emitting movw ASM on certain
test cases (found building qmake4/5 for ARM). Don't do that, moreover, the AS
in base doesn't understand this instruction for this target. One would need
to use --integrated-as to get this to build if desired.
