Dear Jan,
I am using the toolchain from pre-built toolchain from CodeSourcery.
Using built-in specs.
Target: arm-none-linux-gnueabi
Configured with: /scratch/paul/arm/src/gcc-4.2/configure
--build=i686-pc-linux-gnu --host=i686-pc-linux-gnu
--target=arm-none-linux-gnueabi --enable-shared --enable-threads
--disable-libmudflap --disable-libssp --disable-libgomp
--disable-libstdcxx-pch --with-gnu-as --with-gnu-ld
--prefix=/opt/codesourcery --enable-languages=c,c++ --enable-symvers=gnu
--enable-__cxa_atexit --with-versuffix=CodeSourcery Sourcery G++ Lite
2007q1-10 --with-pkgversion=CodeSourcery Sourcery G++ Lite 2007q1-10
--with-bugurl=https://support.codesourcery.com/GNUToolchain/ --disable-nls
--with-sysroot=/opt/codesourcery/arm-none-linux-gnueabi/libc
--with-build-sysroot=/scratch/paul/arm/install/arm-none-linux-gnueabi/libc

--with-build-time-tools=/scratch/paul/arm/install/arm-none-linux-gnueabi/bin
--with-build-time-tools=/scratch/paul/arm/install/arm-none-linux-gnueabi/bin
Thread model: posix
gcc version 4.2.0 20070413 (prerelease) (CodeSourcery Sourcery G++ Lite
