Oddities in ECL tests on Linux

[Robert Goldman]

Unfortunately, this patch doesn't seem to work.  Maybe it interferes 
with condition handlers?  At any rate, after I insert it into 
script-support.lisp I now get two *new* test failures in 
package-inferred-system-test.script and 
test-defsystem-depends-on.script.  I get a message that

```
Top level in: #<process TOP-LEVEL>.
ECL unexpectedly landed in the top level prompt. Script aborted.
Using ecl, package-inferred-system-test.script failed
```

...and one like it for the other test.  So there were some failures 
there that were correctly caught before that are no longer.
