The manpage is quite clear in the
local-script-is-copied-into-the-builder respect, but I looked at
pbuilder --help instead:

    pbuilder --login
    pbuilder --execute -- [command] [command-options]
      Logs in to the build environment and execute command.

And, well, a command is something residing in the builder (imho).

Actually using a "script" or a 32bit binary works fine, -- does not
matter, the problem is that the i386-builder can't execute a 64bit
program (because libraries are missing), but the error message is more
than unclear. E.g. this does work:
sudo pbuilder execute --basetgz /tmp/base-sid-i386.tgz -- \
    /chroot/sid-i386/bin/echo hello world
something I would have (until yesterday) expected to fail because that
path does not exist in the pbuilder.
