[LTP] [LTP PATCH]: two realtime test cases rttester and pi_test

[Yi C. Y. <yya...@cn...>]

Hi, Michael

This is a update for last patch, it includes some READMEs and check codes 
for the Linux kernel version and glibc version, they can be installed 
gracefully although glibc 2.5 and 2.6.18 aren't available, in this case, 
these test cases will output error information and exit.

The whole patch is very large, it is attached in this email. The diffstat 
is below:
