This is really a separate discussion, but my take on it is that
the goal is to have warning-free builds on all platforms. Turning
this feature off for some targets would hide those warnings away,
and reduce our chances of anyone working on them. Building
a snapshot of the day is considered to be building GDB in developer
mode, so the warnings are fatal by default. If you were to build
from a release or from a release branch, on the other hand, the
configure settings have been changed to make the warnings non-fatal.

Note that having a warning-free build is not entirely within GDB's
control. For instance, you'll need a certain version of bison for
it to generate files that compile warning-free. I don't believe
it is worth spending time trying to come up with a list of tests
that will tell us whether warnings should be fatal or not.

I'm not a specialist, but I don't think codesigning can happen
automagically. Codesigning requires for instance the name of
a certificate, which is yours to choose. Creating that certificate
involves the use of graphical tools. That's why we left the codesigning
to the user - especially since the binaries are transportable but
the codesigning needs to be redone on every machine to match the
certificates provided by each machine.
