<p>this check is bogus and should be removed<br>
it breaks usage for example when CXX is set to <code>arm-linux-musleabi -isystem /sysroot/foo</code></p>

<pre><code>$ which g++ -isystem foo
/bin/which: unrecognized option: i
BusyBox v1202 (2015-04-23 14:57:49 CEST) multi-call binary

Usage: which [COMMAND]

Locate a COMMAND
