(Heh -- missed -i when I skimmed through the man page...)

I guess --ignore-errors wouldn't abort the single allproducts target, but
it's still not what I want.

 - Any error in the first part, where the many binaries are being built,
should abort the whole build.  It's in the second part that I want to get as
many products assembled as possible, irrespective of any products failing.

 - I still want the build to report any product-assembly failures
(specifically, exit with a non-zero code), so that they get noticed and fixed.

 - The description of -i talks about "commands executed to rebuild files" but
I want this to work on clean builds.  (Perhaps I should mention that the main
user of this "allproducts" target is a build bot, not a human.)
