Hmm, doesn't help unfortunately.  A full command line for me looks like:

x86_64-pc-linux-gnu-gcc -c -o pbeampp.o -DSPEC_CPU -DNDEBUG  -DWANT_STDC_PROTO 
-Ofast -march=znver4 -mtune=znver4 -flto=32 -g -fprofile-use=/tmp
-SPEC_CPU_LP64         pbeampp.c.

Could you verify if it's exactly the same for you?  Maybe it would also help if
you explicitly specified znver4?
