8 # Toolchain wrapper script.

10 # This script allows us to use a small number of GCC / binutils cross-tools
11 # (one toolchain per instruction set architecture) to implement a larger
12 # number of processor- or board-specific tools. The wrapper script is
13 # configured at install time with information covering basic CFLAGS,
14 # LD options and the toolchain triplet name.
