* ld-bootstrap/bootstrap.exp: If not in the ld build directory,
call untested for each test, rather than ignoring it. If one test
fails, go on to the next one instead of returning.
* ld-cdtest/cdtest.exp: If compilations fail, mark tests as
unresolved.
* ld-empic/empic.exp: Likewise. Also, always pass the same test
name to pass or fail.
* ld-shared/shared.exp: Likewise. Also, always run all tests.
* ld-scripts/defined.exp: If as or nm fail, mark test as
unresolved. Always pass the same test name to pass or fail.
* ld-scripts/script.exp: Likewise.
* ld-scripts/sizeof.exp: Likewise.
