build with 64-bit fsblkcnt_t on 32-bit glibc platforms 
It is possible to build with 64-bit file offsets on 32-bit platforms such as
armv7, and indeed this is the default for some build environments such as
Yocto. Use fsblkcnt_t, which is an alias to a type of the correct width, when
computing blockSize.
