Good morning, Frode!

I just tried to build latest git with LTO enabled and optimizations for my native CPU (AMD Bulldozer first generation). It builds fine until the final link stage.

I configured build as:
Code:
./configure CFLAGS='-flto -march=native -mtune=native' CXXFLAGS='-flto -march=native -mtune=native' CPPFLAGS='-flto -march=native -mtune=native' LDFLAGS='-flto'
Error at end:
Code:
