I ran into this problem while upgrading to gcc-3.2 (of which I am still
in the process of; 2 days so far). I tried every make instruction I
could find: clean, mrproper, etc. I have not had a chance to reboot to
see if the kernel I made worked, but the only way I got "make modules_install"
to shut up was by configuring nothing to be used as a module.

Note also, gentoo-sources is
broken (http://bugs.gentoo.org/show_bug.cgi?id=6787) but the
vanilla-sources still work. And, linux-headers, which are needed
for glibc, is out of date with respect to the vanilla-source
(http://bugs.gentoo.org/show_bug.cgi?id=6793).
