Benchmark code that depends on the state of LITE-related symbols has this dependency removed, and is now coded as if these symbols are not defined. This change has no operational impact, as LITE- related symbols were never defined. Change-Id: I9b9a108223903b8e4dd675a599ca5b8e5cbe7fc7 Signed-off-by: Allan Stephens <allan.stephens@windriver.com>
