Summary:                    'Use of uninitialized value $ENV{"XBUS_NAME"}' if
stderr from make redirected to a file
Description: 
The init scripts of the xpp drivers (drivers/dahdi/xpp/init_card_X_30)
should be run from a context that sets a number of environment variables. 

init_card_2_30 can also be run from the command-line for verification
purpose. The script tests that it is run from the command line using the
following test:

  if (-t STDERR) {

That is: if the standard error is a terminal. This test will fail is
several automated build environments. Or even by a casual run of:  'make
2>log'

Workaround: if the test fails, generate the flag file that shows it was
successful and assume that is was :-(

  touch drivers/dahdi/xpp/init_fxo_modes 
  touch drivers/dahdi/xpp/init_fxo_modes.verified
