I think it's clear i didn't.

The OP configure line is a massive dump of pointless "--disable" options
typical from Gentoo builds, so i didn't even bother looking at it for
specific things. And now that i look at yours they are completely
different as well, so perhaps it doesn't depend on configure options but
something else, like target.
