Created attachment 462840 [details] build.log
Reported upstream.
Created attachment 465354 [details, diff] remove nested comments in blake2s-load-xop.h simple patch that removes the nested comments and make python-3.6.0 compile on my system with -march=bdver4
here the same: System: Linux-4.9.4 x86_64 AMD A8-7600 Radeon R7 CFLAGS="-march=native -mno-tbm -O2 -pipe" gcc --version gcc (Gentoo 5.4.0-r3 p1.3, pie-0.6.5) 5.4.0 and compile with the patch provided by johannes as well.
*** Bug 611730 has been marked as a duplicate of this bug. ***
Same problem with python-3.6.1. The patch fixes it there too.
*** Bug 620296 has been marked as a duplicate of this bug. ***
I confirm that the patch attached here as attachment #465354 [details, diff] works to get dev-lang/python-3.6.1 to compile. I would suggest to p-mask dev-lang/python:3.6 until this is resolved.
(In reply to Dennis Schridde from comment #8) A build failure that is easy to work around does not warrant an entry in package.mask.
