configure script couldn't find the specific file ( compiler executable) under /tools/lib directory so you got the message "fatal error: no input files". I think, your /tools/lib directory is empty or wrong path for executable.
The -B option used in gcc to find the executables, libraries, include files, and data files of the compiler itself. And configure script couldn't find the executable so unable to compile the conftest.c so there is no file like a.out. But confusion is here "configure:4066: $? = 0" why return 0?
