JDK 9 can no longer be built for the arm vfp softfp ABI.

If you run configure specifying this api-profile, the C1 hotspot VM build will fail.

    --with-abi-profile=arm-vfp-sflt

hotspot/src/cpu/arm/vm/c1_FrameMap_arm.cpp: In static member function ‘static void FrameMap::initialize()’:
hotspot/src/cpu/arm/vm/c1_FrameMap_arm.cpp:182:22: error: ‘single_softfp’ is not a member of ‘LIR_OprFact’
hotspot/src/cpu/arm/vm/c1_FrameMap_arm.cpp:183:23: error: ‘double_softfp’ is not a member of ‘LIR_OprFact’
