LibBSD | 7-freebsd-14 does not compile for powerpc (beatnik) (#67)

[Heinz Junkes (@junkes)]

Heinz Junkes created an issue: https://gitlab.rtems.org/rtems/pkg/rtems-libbsd/-/issues/67



## Summary

I'm trying to build libbsd for my target beatnik.

rsb from main (https://gitlab.rtems.org/rtems/tools/rtems-source-builder)

Kernel from main, use POSIX API

```
git clone https://gitlab.rtems.org/rtems/rtos/rtems.git kernel
cd kernel
./waf bspdefaults --rtems-bsps=${RTEMS_CPU}/${RTEMS_BSP} > config.ini
sed -i \
-e "s|RTEMS_POSIX_API = False|RTEMS_POSIX_API = True|" \
-e "s|BUILD_TESTS = False|BUILD_TESTS = True|" \
config.ini
```

```
