So why not this?

noinst_HEADERS =
if PROG1
noinst_HEADERS += ...
else
noinst_HEADERS += ...
endif

if PROG2
noinst_HEADERS += ...
endif

Really adding files to noinst_HEADERS isn't much different from just
adding them to EXTRA_DIST.

I agree that the warning 

>>> `noinst_prog_HEADERS' is used but `noinst_progdir' is undefined

is weird.  I'm mostly arguing to avoid having to do the work of fixing
the warning.  ;-)

prog_LDADD is for adding stuff to the link of the program.

prog_DEPENDENCIES is for explicitly listing link dependencies which
automake can not infer from prog_LDADD.
