roms/edk2-funcs: Force softfloat ARM toolchain prefix on Debian

qemu with hax to log dma reads & writes jcs.org/2018/11/12/vfio

The Debian (based) distributions currently provides 2 ARM
toolchains, documented as [1]:

* The ARM EABI (armel) port targets a range of older 32-bit ARM
devices, particularly those used in NAS hardware and a variety
of *plug computers.
* The newer ARM hard-float (armhf) port supports newer, more
powerful 32-bit devices using version 7 of the ARM architecture
specification.

For various reasons documented in [2], the EDK2 project suggests
to use the softfloat toolchain (named 'armel' by Debian).

Force the softfloat cross toolchain prefix on Debian distributions.
