Hi Paul, I assumed we don't need to remove conftest.obj because it's
not produced by most compilers when the "-o foo" option is used,
although I suppose it can't hurt to remove it as well.  It also seems
we can't use $ac_objext here because this macro AC_COMPILER_EXEEXT
must be run before the macro AC_COMPILER_OBJEXT which defines
$ac_objext, so I think we must simply hardcode conftest.o.
