The sample without tweaks builds just fine here. Can you check that
it is also the case (without your tweaks!) on your side?

Yes, that's because your .config has:
  CT_LIBC="none"

That is, no C library is selected (which may be valid in some cases, but
is not on yours).

Was that a deliberate tweak of yours?
If so, why do you not want to use a C library?

No need to look at this part of the log, the error happens before that. ;-)
