Last change on this file since e6b31b27 was e6b31b27, checked in by Joel Sherrill <joel.sherrill@…>, on May 27, 2015 at 3:13:58 PM

Remove use ticks for statistics configure option.

This was obsolete and broken based upon recent time keeping changes.

Thie build option was previously enabled by adding
USE_TICKS_FOR_STATISTICS=1 to the configure command line.

This propagated into the code as preprocessor conditionals
using the RTEMS_USE_TICKS_FOR_STATISTICS conditional.
