Comment 4 for bug 1309060

The tool chain package included in Ubuntu is actually generated by Debian. Now we are talking with the package's Debian maintainer to see if we can consolidate both sides effort to maintain an unified tool chain. It looks to me that the Debian gcc-arm-none-eabi is also targeting cortex-a/r/m bare metal targets.

Meanwhile we really appreciate if you can list more differences between those two tool chains. We already notice that the Ubuntu gcc-arm-none-eabi doesn't support newlib-nano.
