[PATCH 1/4] deb-pkg: Add automatic support for armhf architecture

[riku.voipio@linaro.org]

From: Ben Hutchings <ben@decadent.org.uk>

The Debian armhf architecture uses the ARM EABI hard-float variant,
whereas armel uses the soft-float variant.  If the compiler used
to compile the kernel uses the __ARM_PCS_VFP ABI, the compiler
targets armhf architecture.

v3 by Riku: Use gcc define instead of CONFIG_VFP
