ARM Linux Toolchain Base:

This file provides the basic work for ARM toolchains running on Linux systems. It uses the CMAKE_SYSTEM_PROCESSOR and ARM_TOOL_SUFFIX variables to determine the names of the tools to search for. These must be set in the calling script. This toolchain will find the ARM tools under the path specified with the ARM_TOOLS_PATH environment variable and if -DCMAKE_SYSROOT=... is specified then this path will be used for searching for libraries/headers to compile against.
