It does run them - or try to, anyway.  It invokes `system' in Perl.
Unfortunately Perl does the wrong thing when you say
 $foo='./t'; system($foo './u');
if ./t isn't a proper executable script.  IMO it should produce a
message to stderr, but it doesn't.  Instead $? is set to 62580 and no
message is produced.
