unrar: strip out native compilation flag
<!-- Uncomment relevant sections and delete options which are not applicable -->

#### Testing the changes
- I tested the changes in this PR: **briefly**

This should get rid of the native compilation flag in the makefile script.

Not sure if it was included upstream by mistake, but it should be looked out for when new versions are released (ie revert this change if the flag gets removed again).

A patch file from https://github.com/void-linux/void-packages/pull/50557.patch is attached
