Curiously when building a cross compiled riscv64 GHC, the libraries (for the target) turn out way bigger than when building a riscv64 cross compiler. Profiling libraries are not necessary for bootstrapping GHC, so we can disable them for now. We may want to revisit this condition, though, once we have a native bootstrapping path for riscv64-linux set up.
