[OpenWrt-Devel] [RFC] brcm2708: enable hard float ABI

[Álvaro Fernández Rojas]

This enables hard float abi on BCM2708 (RPi1) and also enables neon on BCM2709 (RPi2).
Attention: minimally tested, but seems to be OK.
The toolchain directory changes on BCM2709 due to switching the CPU subtype to neon, but BCM2708 needs a distclean.
