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 
week.
