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 and leads to a sizable number of false positives in EAPI 8. I have 937 EAPI 8 packages on my machine, and in 0 cases does my patch now produce static libraries where none were produced before, while it successfully reduces the annoying QA warnings on packages that don't use libtool or use the flag for different purposes: 1. packages that have an "off-target"/false-positive flag triggering the current logic: dev-libs/nspr-4.35 --enable-static-rtl Use the MSVC static runtime library sys-fs/lvm2-2.03.16 --enable-static_link use this to link the tools to their libraries 2. packages with a real --{dis,en}able-static flag, but with semantics that don't actually disable building of static-libs: dev-util/strace-5.19 --enable-static link strace statically sys-process/htop-3.2.1 --enable-static build a static htop binary [default=no] media-video/mkvtoolnix-71.1.0 --enable-static make a static build of the applications (no) --enable-static-qt link to static versions of the Qt library (no) dev-util/strace has a $(use_enable static) option, and the other two are default disabled. Hence in all of these cases, the patch does not change the build output. 3. packages with a --{dis,en}able-static flag that controls building of static libraries, but with a slightly different --help output that doesn't trigger the updated glob anymore: dev-libs/icu-72.1 --enable-static build static libraries default=no dev-libs/nettle-3.8.1 --disable-static Do not build any static library net-print/cups-2.4.2 --enable-static install static libraries All of these packages pass a $(use_enable static-libs static) option, hence none of them would be affected by the missing --disable-static. With this extensive analysis, I believe this patch to be safe.
