[gentoo-amd64] Looks like I broke libc

[Michael Hordijk <hoffbrinkle@hotmail.com>]

Yay.  Somewhere in the course of normal compiling, I've managed to hork 
something up.  I run a plain amd64 system, and usually don't do anything 
funny outside of the stable packages unless I need to.  It appears I've 
broken my glibc installation:

configure:2289: checking for C compiler default output file name
configure:2292: gcc -march=athlon64 -O2 -pipe   conftest.c  >&5
/usr/lib/gcc/x86_64-pc-linux-gnu/3.4.6/../../../../x86_64-pc-linux-gnu/bin/ld: 
skipping incompatible /lib/libc.so.6 when searching for /lib/libc.so.6
/usr/lib/gcc/x86_64-pc-linux-gnu/3.4.6/../../../../x86_64-pc-linux-gnu/bin/ld: 
cannot find /lib/libc.so.6

First let me say that I haven't done anything funny on this system, save 
for updating my profile from 2005.3 -> 2006.0.  I usually don't switch 
profiles without first checking on amd64, but I haven't seen anything 
that indicates this is a no-no.  Somewhere in the course of emerge -uD 
world (which I hadn't done in a while), during which both gcc and glibc 
were updated, I got the above problem.

My emerge info:

So I take it I've borked my libraries in one way or another.  What's 
going to take to get them back to usable state?  Other than this, my 
system still seems to run fine.
