Hmm, I doubt it.  But in comparing what you have posted to my AMD64
box, I see some things that don't look right.  For example, on my
AMD64 box, I have:

Gentoo Base System version 1.12.0
Portage 2.1 (default-linux/amd64/2006.0, gcc-4.1.1/amd64-vanilla,
glibc-2.4-r3, 2.6.16 x86_64)
=================================================================
System uname: 2.6.16 x86_64 AMD Athlon(tm) 64 X2 Dual Core Processor 4400+

Notice my profile is default-linux/amd64/<something>, where you have
your profile as just default-linux/amd64.  I'm not sure that is
actually supported...and may in fact be the cause of your trouble.

The new profiles (starting with 2005.1) are "multilib" by default, so
for example merging glibc will try to build both i686 and x86_64
versions.  So it is in fact perfectly reasonble for an emerge of glibc
to try to build a i686 version, but *only* if you are using a multilib
profile.  Similarly gcc would try to build i686 versions of its
libraries, but would require an i686 glibc to be available first.

I suspect what you need to do is:

cd /etc
rm make.profile
ln -s ../usr/portage/profiles/default-linux/amd64/2005.1/no-multilib

Then try re-merging glibc and gcc.

If you want to switch to the multilib profile, the symlink should be
to /usr/portage/profiles/default-linux/amd64/2005.1 or 2006.0.  But
you might want to ask on gentoo-amd64 about how to switch from
no-multilib to a multilib profile...
