USE_ARRAY_FOR_64BIT_TYPES logic broken ?

[Mike Frysinger]

i was cross-compiling file-4.16 for an amd64/uClibc host and when i tried to 
use it natively, it kept giving me crap like:
/bin/bash: ERROR: error seeking (Invalid argument)

i traced it back to configure setting the size of all the uint types 
(8/16/32/64 bits) to 0 because it was a cross-compile, thus forcing the logic 
of USE_ARRAY_FOR_64BIT_TYPES to be enabled

for example, this code:
            if (dophn_core(ms, class, swap, fd,
#ifdef USE_ARRAY_FOR_64BIT_TYPES
                (off_t)getu32(swap, elfhdr.e_phoff[1]),
#else
                (off_t)getu64(swap, elfhdr.e_phoff),
#endif
                getu16(swap, elfhdr.e_phnum),
                (size_t)getu16(swap, elfhdr.e_phentsize)) == -1)

that getu32() only swaps & uses the 2nd set of 32bits and disregards the first 
set of 32bits (thus leading to my funky problem of bogus lseek() calls)
