[John Paul Adrian Glaubitz]

Fixes the following build error on 32-bit PowerPC:

kexec/arch/ppc/fs2dt.c: In function 'putnode':
kexec/arch/ppc/fs2dt.c:338:51: error: passing argument 4 of 'scandir' from incompatible pointer type [-Wincompatible-pointer-types]
  338 |         numlist = scandir(pathname, &namelist, 0, comparefunc);
      |                                                   ^~~~~~~~~~~
      |                                                   |
      |                                                   int (*)(const void *, const void *)
