Как я могу преобразовать эту функцию удара в оболочку рыбы

Бэкпортирование для сжимания/стабильного возможно, но нетривиально. Вот патч против файлов в debian каталог, который применяется против 4.7.0-1 Источники Debian в тестировании (должен также работать против, по-видимому, немного отличающейся версии 4.7.0-3 в нестабильном), и должен позволить тому успешно основываться, сжимают, хотя я не протестировал патч непосредственно путем применения его к нетронутым источникам. Очевидно, установка двоичных пакетов от тестирования на конюшне возможна, но не хорошая идея в целом. Выполнение таких вещей является рецептом для нестабильности и побеждает цель использовать стабильный во-первых. Однако бэкпортирование этим способом не должно вызывать дополнительные обновления и не вызывать проблемы с Вашей системой.

Я не вспоминаю изменений внесения в rules.parameters, но большая часть остальной части патча является изменениями, которые я внес, в противоположность сгенерированным изменениям машины. Попытайтесь применить этот патч к источникам Debian и работать debuild binary или подобный. Я мог загрузить патч где-нибудь, если существует интерес, и если получение его из этого сообщения не удобно. Сообщения об успехе и одобренном отказе.

Примечания:

• Это потребует установки набора зависимостей от сборки, но только от сжатия,
  и apt-get build-dep не будет работать, так как зависимости от сборки были локально
  измененный - необходимо будет сделать это вручную.
• Сборка libgcc1-dbg давал ошибки, таким образом, я вынул его.
• Набор тестов имеет некоторые проблемы, таким образом, я отключил их. Посмотрите строки with_check := disabled by hand. Проблемой не является тестовый сбой, но сборка не может найти некоторые файлы связанными с тестами, таким образом, это ошибки.
• Я заменил binutils версией в сжатии, а именно, binutils (>= 2.20.1).
• Я отключил multilib, с тех пор сжимают, не использует его.
• Эта версия была протестирована на amd64, но должна также работать в i386, по крайней мере.
