Единственое, что я могу сказать -- во втором случае не выставляется версия
EABI(старший байт в Flags). Почему так происходит -- сказать сложно.
Возможно, старый и/или плохо собраный binutils.

Покажите с этой машинки
/usr/bin/ld --help | grep supported

Не берусь предсказать.

От ядра требуется лишь поддержка EABI.
