Yes.

Authoritative answer:  "It depends".

On what you 'did wrong", and what it takes to fix it.

e.g.,  if you're building a kernel the 'classial' way, that is 'configure,
make depend, cd , make',  and realize you left something out of the config
file, after you edit the config file, you have to rerun _all_ those steps.
