Hi, I want to provide a general defined macro like __MY__TIME__ (for 
determinictic build) and that symbol should be seen as #define or -D... to gcc 
in all files;

Value of __MY_TIME__ is determined once, at start of build.

I was using file scripts/mkcompile_h as in the attached .diff patch, worked in 
3.2.48 but in 3.2.50 files do not see the value _MY_BUILD__TIME__
