If your target platform requires it, then you may need to set CFLAGS appropriately here, e.g.

If necessary on your platform, you may again need to create a mk/build.mk
to pass any necessary flags to gcc, e.g.:
```wiki

You should also consider putting:
```wiki
SRC_CC_OPTS += -g -O0
``` ```
in `<T>/mk/build.mk`. It'll make the resulting compiler slower, but it'll be a lot easier
if you get segfaults etc later on.
