Yes, that fixes the dependency problem; the build waits for the xsinfo to 
terminate. This at least makes it easy to Ctrl-C and try again. Are we aware of 
any reason why *not* to make that change?

The hang in xsinfo appears to be miscompilation when the host compiler is 
gnat-4.8 (on ARM), whereas gnat-4.6 succeeds. I'm going to try again with later 
versions (4.9/5.0/etc.)...
