Change "uname -i" to "uname -m" to be portable
Change "uname -i" to "uname -m" to be portable

According to the documentation for uname:

       -m, --machine
              print the machine hardware name

       -i, --hardware-platform
              print the hardware platform (non-portable)

So use the portable -m version.
