Well, I had to make a couple of patches to the configuration to get the
Libera EPICS driver (my ARM test application) to build.
This patch is rather important. The line removed by this patch has a
very strange effect: it adds makefile rules of the form
$(action).$(arch): $(action).$(EPICS_HOST_ARCH)
specifically, it adds the rule
install.linux-arm: install.linux-x86
to my build. The effect of this rule is that in order to build my
linux-arm IOC, I have to first build a linux-x86 version of the IOC, and
more generally, all cross-compiled IOCs depend on having a native IOC
build succeed first. This isn't going to work.
Somehow this seems ... mistaken. I don't see what this line is trying
to achieve ... but then complex Makefiles are barely comprehensible at
the best of times.

Patching CONFIG.Common.linux-arm. This patch is arguable, but I'm not
sure that such target specific architecture flags belong in EPICS base.
The line removed by this patch crept into 3.14.10, and breaks the Libera
build.
