Sanity check with external args

Previously cross, but not native, external args were used. Then in
d451a4bd97f827bb492fd0c0e357cb20b6056ed9 the cross special cases were
removed, so external args are never used.

This commit switches that so they are always used. Sanity checking works
just the same as compiler checks like has header / has library.
