Upstream code contains "always inline" instructions that require AVX
Fatal compilation errors with -march=k8-sse3
Builds with -march=native on a Kaveri and bulldozer.
This is an upstream bug, but I think the ebuild should test for the existence of the AVX instruction.

For what it's worth: I've built dev-qt/qtmultimedia-5.12.3 on an AMD Phenom II X6 1055T without issue and it does not have AVX instructions. -march=native on this machine as well. CPU_FLAGS_X86: mmx mmxext popcnt sse sse2 sse3 sse4a

Builds as native but not as older cpu

AVX assumption based on google search. Will attempt to build as k10. Repeat, will not build as k8, but will build as native (bulldozer/kaveri).
ebuilds should build on base amd64 or check for instructions needed.
Also blows up building with march=amdfam10.
Also blows up with no march (should default to minimal x86_64
works with march=bdver1
