https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: dev-libs/libaio-0.3.113 fails to compile (lto). Discovered on: amd64 (internal ref: lto_tinderbox) NOTE: This machine uses lto with CFLAGS=-flto -Werror=odr -Werror=lto-type-mismatch -Werror=strict-aliasing
Created attachment 789449 [details] build.log build log and emerge --info
Error(s) that match a know pattern in addition to what has been reported in the summary: {standard input}: Error: invalid attempt to declare external version name as default in symbol `io_queue_wait@@LIBAIO_0.4' lto-wrapper: fatal error: make returned 2 exit status
Created attachment 800669 [details] Preposed ebuild As upstream have stated they don't plan to fix this as they can't see any benefit to LTO for this library then I think the best option is to just filter the -flto flag until that stance changes.

We need to use the new 'filter-lto' from flag-o-matic. Thanks, I'll commit that variant.
