haskell.compiler: also build manual for cross-compilers

The reasoning given for disabling it is flawed: In most cases, sphinx
and its dependencies are already in the binary cache, since we only need
them as build tools—sphinx for the build platform is just the normal
pkgs.sphinx, since it doesn't care about targetPlatform.

We just need to disable it when the buildPlatform is also musl, so we
avoid pulling in sphinx in pkgsMusl.
