coreutils-5.92:du not AIX largefile safe --

[Paul Townsend]

=====
When the `du' included with coreutils-5.92 is compiled on an AIX 5.1 box
that has a 32 bit kernel and is compiled with large file support, it
incorrectly computes the size of a file that exceeds 2**31-1 bytes.  If
I've interpretted the code correctly, it's because the stat->st_blocks
entry is a signed int that's multiplied by 512 before being promoted to
an unsigned long long (uintmax_t).  The patch below forces the promotion
before the multiplication.
