Linux: Remove hardcoded lib path for x86 cross-compilation
This breaks the build with our updated i686 Linux SDK which doesn't contain this path, and may not be needed at all. This might need further work to be robust, and there's an open PR already adding -march flags for all supported architectures, but for now we're playing it safe for 4.2.
