Adjustments for /dev/pts

1. Declare UNIX98 PTY requirement in host system requirements and check it in the script. All desktop or server distros should have it now, but let's stop anyone from building on a embedded distro w/o UNIX98 PTY early...
2. Use Expect test suite as a guard against mishandled $LFS/dev/pts.
3. No need to test the basic function of Expect in Binutils anymore because if ($LFS)/dev/pts is not good, the Expect test suite would have failed.
