This toolchain uses -mfloat-abi=softfp (i.e can use FPU
instructions, but passes floating point function arguments
in integer registers), and requires a VFPv3 floating point
unit to work properly. This unit is available on most
Cortex-A ARM processors, but not all.

Toolchain based on the Musl C library, provided by the
musl-cross project. It uses gcc 5.3, binutils 2.25.1 and
musl 1.1.12. It does not have a cross debugger included.
The ARM soft-float toolchain is built for ARMv4t, while the
ARM hard-float toolchain is built for ARMv5t.
The x86 toolchain is built for i486.
