Right, then this is a consequence of something I'm trying to repair....
I thought I build world+kernel.
So I installed kernel and rebooted,
Only to find out that instalworld did not make it very far.

After that I started fidgeting, hoping to somehow get to 10.1.

So my guess is that things get very upset if one is building on a system
with a 10.1 kernel, and a 9.3 world.

GROUP ( /lib/libc.so.7 /usr/lib/libc_nonshared.a
/usr/lib/libssp_nonshared.a )

So that seem to be the case

I just manually went into /usr/src/lib/libc_nonshared and ran
	make
	make install

And now I'm trying to build world on a 1.8GHz atom, so that is slow....
Even just compiling clang is already a serious undertaking.
