--- Comment #2 from Mathieu Malaterre <mathieu.malaterre at gmail dot com> ---
I've downgraded binutils to version from bullseye, and I am getting the exact
same symptoms:
```
libtool: link: ( cd ".libs" && rm -f "libkcapi.la" && ln -s "../libkcapi.la"
"libkcapi.la" )
/bin/bash ./libtool --tag=CC --mode=link hppa-linux-gnu-gcc -g -O2 -fpie
-fPIE -DPIE -Wl,-z,relro,-z,now -pie -o bin/kcapi-rng
apps/bin_kcapi_rng-kcapi-rng.o apps/bin_kcapi_rng-app-internal.o libkcapi.la
