gcc 15 defaults to the C23 standard, where bool, true and false are
keywords. The am33x-cm3 code base defines them in its own stddef.h,
so the build fails with:
src/include/stddef.h:18:15: error: 'bool' cannot be defined via 'typedef'
18 | typedef _Bool bool;
| ^~~~
src/include/stddef.h:19:8: error: cannot use keyword 'false' as enumeration constant
19 | enum { false, true };
| ^~~~~
The upstream project has not received any commit since 2018 and none
of its branches fix this issue, so rather than carrying a patch that
cannot be submitted to an active upstream, force the GNU C11 standard
in the .mk file.
