3.4.2 build log

Only CFLAGS="-march=native" . No -flto, no -O3, no -pipe etc.
Comment 3 cryptopsy 2018-04-29 23:37:32 UTC 
might be related to gcc LTO , with this env file , it compiles:

CFLAGS="-O2 -march=native -fomit-frame-pointer -finline-functions -fsched-pressure -ftree-loop-distribution -pipe -floop-interchange -floop-strip-mine -floop-block -fgraphite-identity" 
CXXFLAGS="${CFLAGS}" 
LDFLAGS="-Wl,-O2 -Wl,--as-needed -Wl,--hash-style=gnu -Wl,--sort-common -Wl,--strip-debug ${CFLAGS}"
