What do

  ulimit -n
  ulimit -Hn

say?  On Debian systems the soft limit appears to be 1024 by default. 
That's apparently too low now for building llvm, so try increasing it.

  ulimit -n 4096

The procedure for setting the default value may vary by system.  On 
Debian sytsems, edit /etc/sysctl.conf and add/change the value for

  fs.file-max=4096

The value should change on the next system restart.

I did this for the buildbot systems that are doing Windows builds 
because we were having the same problem there.
