Yes, interesting indeed.  I'm on FreeBSD-12.2 (amd64), fully updated.

Circumventing the ports machinery:

tar xvf Python-3.9.1.tar.xz
cd Python-3.9.1
./configure CC=clang --with-system-libmpdec
[...]

And I can't find any system header that typedefs uchar:

[stefan at freebsd-amd64 ~]$ find /usr/include -type f | xargs grep -n
"typedef.*uchar"
/usr/include/c++/v1/atomic:493:typedef atomic<unsigned char>      atomic_uchar;
/usr/include/c++/v1/atomic:2390:typedef atomic<unsigned char>     
atomic_uchar;
/usr/include/sys/stdatomic.h:189:typedef _Atomic(unsigned char)        
atomic_uchar;
