This is indeed OK for packages such as evtest that don't have, or don't
have many, reverse dependencies. But this is hardly a sustainable
solution in general, especially for packages that have a high number of
reverse dependencies.

We simply can't handle all the little possible variations of uClibc
configurations that exist in every external toolchain, it's not
workable in a general fashion.

I know we're already doing it to some extent, but I'd like to avoid
doing it when possible, especially when we have a good cooperation with
the upstream developers (in this case, the Synopsys folks).
