This is not a place to discuss "how do  I  build  my  own  toolchain"
problems.  There  are  existing, known to be working toolchains (like
the EKLDK), there are working build scripts (like  crosstools),  etc.
Many  working  options. If you chose to use a non-working one this is
off topic here.

Why would you need HW FP for a ARM system? Have you access to an  ARM
processor with FPU? Which one is this?
