If I use "mtune=native" instead of "march", final gcc command is different:

/usr/libexec/gcc/i686-pc-linux-gnu/4.6.1/cc1 -quiet - -D_FORTIFY_SOURCE=2
--param l1-cache-size=32 --param l1-cache-line-size=64 --param
l2-cache-size=2048 -mtune=generic -quiet -dumpbase - -march=i686 -auxbase-strip
/dev/null -o /tmp/ccs2Uhin.s


Not sure if that is normal
