Subject: Mount the devpts file system.

The lack of a devpts file system was causing mysterious GNU Binutils
test suite failures, with these "spawn failed" errors in the test log:

    Test Run By root on Sun Dec  8 20:36:45 2013

After spelunking through Binutils and DejaGnu code (exploring the great
remote_exec and local_exec procedures of DejaGnu), I tried the
following, which resulted in much more helpful information:

    $ expect
    expect1.1> spawn echo hello
    spawn echo hello
    The system has no more ptys.  Ask your system administrator to create more.
        while executing
    "spawn echo hello"
