Subject: fixdep ought to be compiled with -D_FILE_OFFSET_BITS


Because fixdep is compiled without -D_FILE_OFFSET_BITS=64,
a 32-bit fixdep (in a chroot build root, for example) may fail to run
on a 64-bit host system if any file has an inode larger than 2^32,
which can easily happen (in my case, on xfs):
