Building RISC-V BSP

[Hesham Almatary]

Hi Denis,

I submitted two patches for the tools, please use the latest only and
rebuild the tools. This should avoid the newlib issues you had above
as it uses main riscv patches.

I'll look into the port this weekend and submit fixes unless you beat
me to it. Meanwhile, you can submit error messages and I'll see if I
can help.

Keep the good work.

Cheers,
Hesham
