I did a few test builds with 'high' CPU values for -march, and I ran

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

That's the problem - libraries miss most symbols.
This is why I still think you have the stdin/out/err problem, in some
way. Can you please check /usr/obj/usr/src/lib/libc/Version.map? It
should have about 2775 lines, otherwise your libc build is busted.
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 ===

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.
