The ARM softfloat library in ArmSoftfloatLib currently does not build under RVCT, simply because the code includes system header files that RVCT does not provide. However, nothing exported by those include files is actually used by the library when built in SOFTFLOAT_FOR_GCC mode, so we can just drop all of them.
