+Description: Move 32-bit support logic to support armhf
+ The logic to support 32-bit architectures was correctly written (define
+ _LARGEFILE64_SOURCE) but placed too "late". If a standard library header
+ (e.g., <stdio.h>) is included before _LARGEFILE64_SOURCE is defined, then
+ the correct symbols will not be made available during compliation. In this
+ instance, armhf builds were failing due to off64_t not getting defined
+ correctly.
