Subject: [PATCH 2/2] cmake: lemon: allow builds to specify a different
 compiler

Lemon is a host build tool used to generate some syntax files.
When cross-compiling, it needs to be built for the host machine
so allow the build to configure a different compiler for it.

The alternative would be to create a cmake spec for each
toolchain and build lemon separately which is overkill for
such a simple tool compared to just pointing it to $HOST_CC.
