There is indeed something missing in the autobuilder to support for a
limited period the, currently experimental, ELF build and AOF build together
at the same time.

There is already a variable AB_ELFBUILD (set or not set to "yes") to make
some difference in the projects so that's good news but something more is
needed if you want to let this determine the value of AB_SVN as this
is simply grepped from the setvars file in fetch-program.

Maybe the introduction of AB_SVN_AOF for projects which are AOF only and
that this gets used when AB_ELFBUILD is not set to "yes", and in all other
cases continue using AB_SVN (for the SVN stored projects of course).
I've attached a not-tested (!) patch illustrating this.  Would this help ?
