<p>Another option is to set the AVR triple as default target during
config with something like:<br>
</p>
<pre class="code highlight"><code><span id="LC14" class="line"><span class="s">-DLLVM_DEFAULT_TARGET_TRIPLE="avr-unknown-unknown"</span></span></code></pre>
<p>That seems to work quite nicely for some of our own targets here,
provides you with some more test coverage, and avoids having to
build the x86 target.<br>

<p>Cheers,</p>
