commit 5a6f4ac9874cffbf396e444cc29d60ed1d214b14
Author: Tamar Christina <tamar at zhox.com>

    Fix aggressive cleanup of T1407
    
    Summary:
    The aggressive cleanup routine of T1407 is removing files that don't belong to it.
    Constrain the test to only removing files it should by putting all it's generated
    binaries in it's own output folder.
    
    Test Plan: make test -C testsuite/tests/ghci/linking/dyn
