'Russian Doll' rust builds

[Hauke Fath <hf%spg.tu-darmstadt.de@localhost>]

Hi,

I have been less than happy with Dovecot recently, and started playing 
with Stalwart

<https://stalw.art/open-source/>
<https://github.com/stalwartlabs/stalwart>
wip/stalwart

Now, the New Way these projects are done, "Nobody walks, everybody 
drives."(*), i.e. you are supposed to run them from a container.

pkgtools/url2pkg did a good job producing a package, but it looks like 
some of the librar^Wcrates start their own c/c++ builds, with autotool 
runs and all, and they are hard to get to.

Upstream recommends clang, but I ran into the same issue with both gcc 
and clang:

[...]

My search Fu has failed me on this. Does the error speak to anybody, in 
particular in the context of a rust build?

Cheerio,
Hauke
