When trying to link fortran-assert, I get this on ppc64el:
```
[ 22%]                   libassert.so
 + flang-21 -shared   -Wl,-z,relro -L/usr/lib/powerpc64le-linux-gnu/fortran/flang build/flang-21_3A97A147075E76D7/assert/src_assert_m.F90.o -Lbuild/flang-21_2C869400E79A318E    -o build/flang-21_2C869400E79A318E/libassert.so
/usr/bin/powerpc64le-linux-gnu-ld.bfd: cannot find -lflang_rt.runtime: No such file or directory
flang-21: error: linker command failed with exit code 1 (use -v to see invocation)
[ 33%]                   libassert.so  done.
```

Thanks
