No problem; thanks for the quick response.

Declaring

.NOTPARALLEL:

in debian/rules should cause make to run serially when working off of
it but still pass -j to upstream's makefiles.  Also, make supports
order-only prerequisites (a relatively new feature, but available even
in stable); if you declare

build-indep-stamp: | build-arch-stamp

it will take care to complete build-arch-stamp before starting on
build-indep-stamp when building both but still allow building just
build-indep-stamp.

That sounds like it should work as well, thanks.

Thanks for investigating further.
