The only processors tested are x64, x64_64 (without mmx), and ppc.

Huh? The only "time" functions are two calls to mdate in x264.c. 
Those calls can be removed with no side effects.

Your compile warnings appear entirely in your replacement system headers, 
and in functions that fail to be defined in said headers. There's nothing 
I can do about it. (Does your system really not come with fprintf, fopen, 
etc?)
