Before you can build CPython with Tiny C, you need to be sure that Tiny C can:

1) malloc and free arbitrary blocks of memory
2) open and close files and do other file system operations
3) perform trignometric calculations (sin/cos/tan and friends)
4) start threads and subprocesses
5) ascertain the time of day and any other clocks available
6) acquire and release semaphores
etc, etc, etc.

These features are provided generally by the C standard library. Does
Tiny C support all of those? If so, how? Do you include a full
standard library, or link against someone else's?
