I can somewhat emulate support for "Rules-Requires-Root: no" by setting
in ~/.sbuildrc:

  $core_depends = [ 'build-essential:native' ];
  $build_environment = { 'RULES_REQUIRES_ROOT' => 'no', };

Which results in fakeroot not being called, though it still ends up
calling dpkg with arguments to use fakeroot:

  $ grep fakeroot ../u-boot_2019.10~rc4+dfsg-2~20190924~1_amd64.build
  Command: dpkg-buildpackage -us -uc -G -rfakeroot

But since fakeroot wasn't installed, I guess dpkg-buildpackage silently
ignored that option... or never tried to call fakeroot, since the
variables or other settings were set for Rules-Requires-Root?


Of course, it would be very nice if sbuild could just read the
Rules-Requires-Root setting an behave appropriately. :)

Related, I get:

Can't exec "fakeroot": No such file or directory at /usr/bin/sbuild line 262. When running `sbuild` in an unpacked source tree (my host system does not have fakeroot installed). The unpacked source tree is for a package with `Rules-Requires-Root: no` and accordingly, `fakeroot` should be unnecessary. Here `sbuild` could use `dpkg-buildpackage -Tclean` to avoid this problem (which also would work better with the new `Build-Driver` interface)
