# 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.
