Disabling distcc or ccache doesn't help.

[Comment 2 Enrico Tagliavini 2015-04-19 11:46:45 UTC]

Same here, looks CFLAGS related. I have a build host and I don't user -march=native on it, my CFLAGS are

CFLAGS="-O2 -pipe -march=core-avx-i -mcx16 -msahf -mno-movbe -maes -mpclmul -mpopcnt -mno-abm -mno-lwp -mno-fma -mno-fma4 -mno-xop -mno-bmi -mno-bmi2 -mno-tbm -mavx -mno-avx2 -msse4.2 -msse4.1 -mno-lzcnt -mno-rtm -mno-hle -mrdrnd -mf16c -mfsgsbase -mno-rdseed -mno-prfchw -mno-adx -mfxsr -mxsave -mxsaveopt --param l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=4096 -mtune=core-avx-i"

I switched to 

CFLAGS="-march=core-avx-i -O2 -pipe -maes -msse4.2 -mavx"

and it compiled fine.

[Comment 3 François Valenduc 2015-04-19 12:29:33 UTC]

I use distcc, so I used the flags that -march native would select and that gives what is listed in emerge --info.

[Comment 4 François Valenduc 2015-04-19 15:28:29 UTC]

It works also with CFLAGS="-march=corei7 -O2 -pipe -maes -msse4.2 -mavx"
