Uninitialized Value when using Remote Host

[umbrae]

Just heads up:

Use of uninitialized value $arch in string eq at mysqltuner.pl line 709, <>
line 2 (#1)
(W uninitialized) An undefined value was used as if it were already
defined.  It was interpreted as a "" or a 0, but maybe it was a mistake.
To suppress this warning assign a defined value to your variables.

To help you figure out what was undefined, perl will try to tell you the
name of the variable (if any) that was undefined. In some cases it cannot
do this, so it also tells you what operation you used the undefined value
in.  Note, however, that perl optimizes your program and the operation
displayed in the warning may not necessarily appear literally in your
program.  For example, "that $foo" is usually optimized into "that "
. $foo, and the warning will refer to the concatenation (.) operator,
even though there is no . in your program.
