gcc version

when i rebuild the src.rpm with my .rpmrc file i became the error "illegal
instruction", when i create the rpm without the .rpmrc file it works perfectly!
other builds with the rpmrc file (pure-ftpd, mpd, cantata) works!

i use the httpd-2.4.25-3.fc25.src.rpm file 

This is my .rpmrc file:

[builduser@buildsrv]: cat /home/builduser/.rpmrc 
optflags: x86_64 %{__global_cflags} -m64 -march=core2 -mtune=core2
