   8 # Toolchain wrapper script.
   9 #
  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.
