If I do

touch Python/Python-ast.c
time make python

it says

real	0m0.564s
user	0m0.394s
sys	0m0.149s


BTW the Xlinker option is a good example to see why autoconf is needed. 
They were lazy and had a simple switch on `uname` to find the option, 
instead of testing it with the compile-macros of autoconf.

haha :) Good luck with that. Remember, tcc supports x86, x86_64, MIPS, 
ARM, ARM64, and C67, so it is a serious beast.
