build: Fix build on riscv64gc-unknown-linux-musl (#67) 

The configure step for jemalloc fails to recognize the rustc
target `riscv64gc-unknown-linux-musl`:
```
  --- stderr
  Invalid configuration `riscv64gc-unknown-linux-musl': machine `riscv64gc-unknown' not recognized
  configure: error: /bin/sh build-aux/config.sub riscv64gc-unknown-linux-musl failed

```

Add an entry to build.rs to translate between the GNU target and rustc
target in order to work around the mismatch
