The Debian (based) distributions currently provides 2 ARM

* 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 recommend
to use the softfloat toolchain (named 'armel' by Debian).
Force the softfloat cross toolchain prefix on Debian distributions.

Ah cool, this answers my earlier question -- "the GCCx toolchain targets
can use either when building for ARM".
Still not sure if this is a "recommendation" for using soft-float, but
if it works, I'm OK with it.
I'll use "suggests" instead.

The comment has not been updated; it still says hard-float.
Oops.
