This toolchain builder builds a GCC and Newlib-based ARM EABI toolchain using the Sourcery CodeBench Lite sources. This Makefile was originally created to allow building a validated GCC release on Mac OS X, as CodeBench Lite / G++ Lite were only provided for Windows and Linux, but this build also includes some optimizations for Newlib that provide smaller binaries. NOTE: Mentor have indicated that there won't be future ARM EABI releases of the free Lite edition of CodeBench, so the 2014.05 release may be the last. You may also be able to use a modified version of this makefile with the sources Mentor provides with the Professional version of CodeBench (which they plan to continue supporting). If future source releases are made available, this Makefile will be updated for them. If not, we may start to build custom versions of other GCC/Newlib toolchain sources.
