New review comment by Johnnynator on void-packages repository

Comment:
You don't want to mess with CC/CFLAGS, they are already set correctly for cross compiling.
You want to add `--no-run`, so it does not attempt to run the just compiled binaries.

The other problem is, the `build.sh` adds `-g0` to `CFLAGS`, which we don't want. The binaries will get stripped by `void-packages`
