| 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. |
