gcc changed the way that you pass the floating point instruction set,
so instead of -march=armv7-a one should now pass -march=armv7-a+fp
to pick a target CPU that includes vfpv3-d16 FPU.
My guess is that in your case the compiler gets the wrong target CPU
and passes that down to the assembler, which then refuses to build
using FPU instructions.
