Update configure.ac so that we don't need glibc when running ./configure.
For x86_64-pc-gnu we still do not have a working glibc so ./configure will fail
under a freestanding environment. We force ./configure to avoid running
compiled C programs as a test which it is not needed when compiling a kernel.
