 Building `rsync` in a non-standard MacPorts prefix, compilation fails with
 a segmentation fault while compiling `simd-checksum-x86_64.o`:

 ```

 After modifying the port build with SIMD disabled (added --disable-simd):
 ```
 configure.args      --with-rsyncd-conf=${prefix}/etc/rsyncd.conf \
                     --disable-simd
 ```

 ...the port builds fine without issue.
