On ppc64le deb machines, when _not_ cross compiling, `uname -m` reports `ppc64le`, which is typically right. However, the "Debian machine triplet" that is necessary to build correctly uses `powerpc64le` for whatever reason. The cross compile path knows this and is explicit about that. To alleviate that, use `dpkg-architecture` to discover the HOST _CPU_ type, which is what forms the machine triplet. The conditional check for `dpkg-architecture` should be safe and reports the right values for x86 and arm, too; falls back to `uname -m` anyways.

Right... this is messy. Could we make this a little more generic? |

I switchted the approach to dumpmachine, but deb-specific. |
