sys-libs/binutils-libs-2.38-r2: finishes the strip stage with
x86_64-pc-linux-gnu-strip: /var/tmp/portage/sys-libs/binutils-libs-2.38-r2/image/usr/lib64/stIEIWxU/regex.o: plugin needed to handle lto object

can be solved by adding -ffat-lto-objects to the compiler flags

"plugin needed to handle lto object" message should now be completely harmless.

Workaround (calling ranlib on archive) was added to Portage over 3 years ago for bug #603594:

I suppose we can close this then?

Let's keep this open in case someone runs into it again.

Hey, just wanted to open a new bug for this issue. It occurs to any package built with LTO with USE="static-libs". Are you sure it's harmless?

I've had kde-frameworks/kwayland fail to build with -fno-lto if dev-qt/qtgui:5 wasn't built with -ffat-lto-objects, but that's only happened when using the mold linker.
