                    architectures: error: typedef redefinition with
                    different types ('long' vs '__off64_t' (aka 'long
                    long'))

Here is what the recently updated benchmarks/iozone fails like for armv6 builds
based on the updates that were recently made (only listing the first few
warnings but including the one error):

    %lld

powerpc (32-bit) likely would get the same sort of messages, including the
error. The same for other ILP32 FreeBSD architectures: long is only 32-bits but
off_t is 64 bits.

-r418913 of /usr/ports was used for the above under 11.0-BETA2 (so clang
3.8.0).
