With those tweaks (and renaming my
${CLFS}/cross-tools/armv4t-unknown-linux-uclibc directory to be
${CLFS}/cross-tools/armv4t-unknown-linux-uclibceabi), I can build gcc
4.6.1 without anything put the softfloat patch.  The "cannot compute
suffix" problem goes away on its own.

None of the env vars I said to change above get used for anything
important until gcc (binutils uses the triplet but just for the
directory name, I think).  Although, rebuilding binutils after you
change your env may not be a bad idea in the long run, there may be tiny
differences that bite you later.

Try changing those env in your .bashrc, then logging out and back in
(as login shell) as your clfs user.  Delete your gcc-build directory
and do the configure over again.
