The gnuarm.com toolchain works fine but is very old. And although it is based on newlib, the tuple that we used to configure for was arm-elf-linux, which is of course bogus since we aren't building Linux applications.

This patch optimizes for the CodeSourcery G++ Lite 2010.09 ARM EABI toolchain, and assumes that it was unpacked next to the old one. Download here:

(I haven't gotten the Linux Installer to work, so I recommend the TAR.)

And since CC is detected by configure when a valid host tuple is given and that toolchain is sane there's no need for us to hard-code the gnuarm.com compiler name in our Makefile. --- src/Makefile | 11 +++++++---- 1 files changed, 7 insertions(+), 4 deletions(-)
