Fixing 'softvfp+vfpv2' compiling issue for Tb9.2
When compiling with -fpu=softvfp+vfpv2 on Tb9.2 we were getting the segmentattion fault. This seems to be due to the RVCT bug when it comes to using int->float (and reverse) castings. One extra level of indirection (function call) has to be applied. Task-number: QTBUG-4893 Reviewed-by: TrustMe
