перекрестная компиляция библиотеки с помощью buildroot с использованием псевдонима внешней цепочки инструментов code sourcery lite 2011, что приводит к

Есть ли способ обойти эту проблему, сохраняя статическую ссылку? Есть ли параметр CLFAGS или LDFLAGS, который статически связывает все, кроме libgcc_s?
Материалы, которые пробовали до сих пор (помимо чтения соответствующих частей справочных страниц ld и gcc):
CFLAGS="-static -static-libgcc"
CFLAGS="-static -shared-libgcc"
CFLAGS="-static -static-libgcc -Wl,-Bstatic"
CFLAGS="-static -shared-libgcc -Wl,-Bstatic"
После добавления -Wl,-lgcc_s,-Bstatic я получаю огромное количество неопределенных/неизвестных символов... (-Bshared не является допустимым параметром, говорит ld)
