Hey, I already posted results of build without -march at all.

This build was without ccache and CPUTYPE or march. Busted:
=== Version.map ===
FBSD_1.0 {
};
FBSD_1.1 {
} FBSD_1.0;
FBSD_1.2 {
} FBSD_1.1;
FBSDprivate_1.0 {
local:
*;
} FBSD_1.2;
=== Version.map ===
Smoking logs gives this:

And this is purely my fault because I incorrectly redefined CPP.
Great thanks to everyone. I'll try to remember what I have learned this
