We are in the same boat here -- there are a lot of gray areas and dark 
corners with autotools. Bootstrapping of components is one of them, as 
commit 82e18891 message illustrates. And in your particular case, you 
are essentially dealing with bootstrapping a component of a component!

As an additional disclaimer, I know nothing about Yocto :-).

Please consider adjusting Yocto "standard way" to honor and use 
component-supplied bootstrap.sh (instead of autoreconf) when it exists.

Yes, most likely they are, but the differences may not matter to Yocto. 
And if they do matter to Yocto, then Yocto should honor component's way 
of bootstrapping before blindly assuming that autoreconf "works".

Squid bootstrapping does not have options, but even if it had them, 
running autoreconf (without options) would probably ignore them, so this 
is probably not about bootstrapping options.

I am very glad to hear that you are making progress.


Good luck,

Alex.
