There are several ways to solve this.  For one, you could use the interpolating qq operator (acts like double quotes), but then you'd have to double escape things...  Personally, I would rather use concatenation, which isn't pretty either, but somewhat easier to read (IMHO): 

foreach my $SYSTEM (qw(ifeuu1 ifcau1 ifcaa1 mifuat aimuat timeuat)) {
    my $cmd = 'ssh -q '.$SYSTEM.q| perl -e \'print +\( stat \( \"Envs_
+|.$SYSTEM.q|.xml\" \)\)\[9\]\;\'|;
    print `$cmd`;
}

Also note that I used qw() for the hostname list, because what you had were barewords, usage of which is generally discouraged.  qw(foo bar baz) is just a short form of saying 'foo', 'bar', 'baz'.
