Attached a patch to finally fix https://bugs.gentoo.org/814380.
When I opened the bug, it was clear that I intended to only disable
static libtool archive building. Unfortunately, I hadn't done the
necessary due diligence, and it turns out how we detect the
"--enable-static" flag is overly broad
* The intention has always been to only target `configure` scripts that use
libtool, not just any script with a `--disable-static*` option.
* libtool has been using the same `configure` format for at least
the past 15 years (going back to libtool 1.5.22):
1. shared and static libraries
