[PATCH] building lnt tools to test cross-compiling

[Robert Lytton]

Hi Rafael,

I may be able to patch in a dummy interface so that it builds - but being able to run is another matter!
The errors include:
  error: unknown type name 'rlim_t'
  warning: implicit declaration of function 'kill'
  error: use of undeclared identifier 'SIGKILL'
  error: use of undeclared identifier 'SIGALRM'
  error: use of undeclared identifier 'RLIMIT_NPROC'
  warning: implicit declaration of function 'getrusage'
  warning: implicit declaration of function 'getrlimit'
  warning: implicit declaration of function 'setrlimit'
  error: use of undeclared identifier 'RLIMIT_CPU'
  error: use of undeclared identifier 'RLIMIT_STACK'
  error: use of undeclared identifier 'RLIMIT_DATA'
  error: use of undeclared identifier 'RLIMIT_FSIZE'
  error: use of undeclared identifier 'RLIMIT_CORE'
  error: use of undeclared identifier 'RLIMIT_NOFILE'
  ...

thank you
robert

What is the error? Maybe we could fix it?
