That's all it gave me.

I played with the config options a bit and got it to build with the 
attached config.

However, now when I run it without any args (just "./linux") I get the 
following:

Checking that ptrace can change system call numbers...OK
Checking syscall emulation patch for ptrace...missing
Checking PROT_EXEC mmap in /tmp...OK
UML running in TT mode
tracing thread pid = 8963

And it just sits there.  If I then hit ctrl-C I get the following:

remove_umid_dir - actually_do_remove failed with err = -2
Tracing thread segfault at address 0xbfffc000, ip 0xa018da40
