Fix test suite failures reported by Pierre in

<http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
* lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
the compiler created a file "b.out" when it didn't create anything
at all.
* lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
Discard stderr too, when invoking the test script.
