[LTP] [PATCH 0/2] lib: Add TINFO_WARN

[Li Wang]

Hi All,

I come up with a way to define simple macros for all LTP print, especially
for TFAIL
we could make use of the GET_MACRO to select a specific macro implementation
based on the number of arguments provided to a variadic macro.

Something partly like:
