All ARM sample now build with gcc-4.3.1! :-)
Unfortunately (fortunately?), this implies using a uClibc snapshot.

 # GMP and MPFR libraries config options

 menu "GMP and MPFR"

 config GMP_MPFR

     bool

     prompt "GMP and MPFR"

     help

       Recent gcc needs both GMP and MPFR to build some frontends.

       Say 'Y' here if you want to build those two libraries specifically

       for crosstool-NG.

       The packages that can use GMP and MPFR are:

         - binutils

         - gcc

         - gdb

 config GMP_MPFR_TARGET

     bool

     prompt "Build libraries for the target"

     depends on GMP_MPFR

     default n

     help

       Also build libraries for the target. This can be usefull if you want

       to later build a compiler that will run on the target, or if you want

       to run gdb natively on the target.
