Build Log
CET is now optional[1] (off by default), but if you happen to need it on your system you can re-enable with USE=cet (try that).
It sounds like there's a need to for a better way to handle this, but the ebuild comment states:
# Allow user to opt into CET for host libraries.
# Ideally we would like automagic-or-disabled here.
# But the check does not quite work on i686: bug #760926.
$(use_enable cet)

The failure is unexpected. Probably a misinterpretet configure failure on binutils side. Can you also attach /var/tmp/portage/sys-devel/binutils-2.35.1-r1/work/build/configure-libiberty/config.log as well?

config.log
(In reply to Worx from comment #6) > I tried both : Oh hadn't noticed flag is masked, so that won't do anything as-is, my bad. Probably best wait to see what slyfox has to say about this now that have the config.log Does look kind of identical to what was supposed to be fixed, --disable-cet prevents the asm test but doesn't affect the -fcf-protection=none test and then it complains cet is force-disabled.

It should be a matter of placing it to /etc/portage/patches/sys-devel/binutils (I hope there will be no conflicts). No Conflict, it works with the patch.
