<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">ghc/mk: don't build gmp packages for BIGNUM_BACKEND=native

Before this change make-based `BIGNUM_BACKEND=native` build was failing as:

```
x86_64-pc-linux-gnu-gcc: error: libraries/ghc-bignum/gmp/objs/*.o: No such file or directory
```

This happens because ghc.mk was pulling in gmp-dependent
ghc-bignum library unconditionally. The change avoid building
ghc-bignum.
