OK to drop build-deps on packages ghc now conflicts with?

[Colin Watson <cjwatson@debian.org>]

ghc 7.8 has some new conflicts, such as libghc-binary-dev.  Would it be
OK to drop build-dependencies from packages that build-depend on these
as I encounter them?

(Background: Ubuntu is using an ancient version of sbuild that chokes on
this.  We're almost ready to upgrade this to something modern, probably
in a couple of weeks, but it seems that maybe in these cases we could
remove the extra build-dependencies anyway.)

Thanks,
