[LTP] About "realtime" build failure

["Mitani" <mitani@ryobi.co.jp>]

Hi,

Build error occured with recent git "ltp-a997c94.tar.gz".
This failure was caused by "realtime" as follows:
------------

I confirmed that above error is dissolved by following revision:

Is realtime necessary? 
Please revise it if there is not problem.
