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