Correct, ARM EABI support has only gone into the 'official' branches of
gcc/binutils/glibc very recently.  If you check the archives for this
list over the past couple of months, you'll find several crosstool
patches to get it working with pre-release binutils, etc.

CodeSourcery, OTOH, produced toolchains with EABI support prior to
getting it merged into the 'official' branches.

If you can find their previous releases somewhere, and look for one that
matches your glibc, you can give that a try.

Hope this helps
