установить глобальные пути поиска по умолчанию gcc

при беге

arm-none-linux-gnueabi-gcc -print-search-dirs | grep libraries | sed 's/:/\n/g'

Получаю следующий результат:

libraries
 =/opt/codesourcery/lib/gcc/arm-none-linux-gnueabi/4.4.1/
/opt/codesourcery/lib/gcc/arm-none-linux-gnueabi/4.4.1/../../../../arm-none-linux-gnueabi/lib/arm-none-linux-gnueabi/4.4.1/
/opt/codesourcery/lib/gcc/arm-none-linux-gnueabi/4.4.1/../../../../arm-none-linux-gnueabi/lib/
/opt/codesourcery/arm-none-linux-gnueabi/libc/lib/arm-none-linux-gnueabi/4.4.1/
/opt/codesourcery/arm-none-linux-gnueabi/libc/lib/
/opt/codesourcery/arm-none-linux-gnueabi/libc/usr/lib/arm-none-linux-gnueabi/4.4.1/
/opt/codesourcery/arm-none-linux-gnueabi/libc/usr/lib/

и при кросс-компиляции некоторых пакетов мне НАМНОГО легче было бы добавлять к этим путям. Я знаю о параметре -L и хотел бы его использовать, но многие пакеты не соблюдают его при кросс-компиляции, более того, использование его с исходным кодом вызывает проблемы. (подробности см. в конце этого поста). В основном у меня есть целое дерево каталогов со всеми необходимыми файлами для компиляции пакетов, и я хочу добавить это дерево каталогов к путям поиска по умолчанию. Например, чтобы -print-search-dirs также выводил путь, подобный следующему:

/target/usr/lib
/target/lib

в дополнение к уже перечисленным путям. Я не ищу конкретного ответа на исходный код, поскольку у меня есть несколько наборов инструментов, с которыми я могу работать.

Для тех, кому интересно, вот ошибка при установке кода:

arm-none-linux-gnueabi-gcc test.c

работает

arm-none-linux-gnueabi-gcc -L/usr/arm-unknown-linux-gnueabi/usr/lib test.c 

не работает с:

/lib/libc.so.6: file not recognized: File format not recognized
collect2: ld returned 1 exit status

так что очевидно, что он захватывает libc с хоста. Я видел, как это происходило с более чем одним набором инструментов, но не со всеми.

В ответ на комментарий: Вот результат для

arm-none-linux-gnueabi-gcc -L/usr/arm-unknown-linux-gnueabi/usr/lib test.c -v -Wl,-verbose
