It's even more complicated than that though; once we get Base to only
build the PVA modules for some target architectures and not for others,
how are the Makefiles in downstream modules such as AreaDetector
supposed to be set up to only build things that depend on PVA for
targets that have PVA built?
areaDetector already handles this. All of its Makefiles have constructs like this for things that depend on PVA (aka EPICS_V4).
ifeq ($(WITH_EPICS_V4), YES)
DBD += NDPluginPva.dbd
INC += NDPluginPva.h
LIB_SRCS += NDPluginPva.cpp
endif

I will try to implement something. My first attempt failed for the
reason Andrew outlined. It is not possible to simply skip the all PVA
modules for a specific T_A because at that time T_A is not yet defined.
A flag needs to be checked inside every module.

After thinking this over last night I now think it would be much more
complex and invasive than the original idea appears. It certainly isn't
going to be possible in the 7.0.1 release.
If you want to use EPICS 7, I think you will have to upgrade your
devices to run on a fully supported OS; partial support like this is
likely to be too invasive to be cost-effective.
