Исправление teod0r, 09.12.22 10:12 (текущая версия) :

стал пересобирать с поддержкой мультилиб по этой инструкции -> https://www.linuxfromscratch.org/~thomas/multilib/index.html
возникли вопросы: почему там есть пакеты кроме glibc, которые собираются с 32-битами (bzip2, file, libcap, util-linux, ..., наверное каждый второй), в то время как в CRUX из 32-битного — тока glibc? вобщем, я стал собирать из 32-битного тока glibc.
а gcc , binutils — с флагом --enable-multilib. и я не собирал совсем x32. это не правильно?

при сборке file (глава 8.10.) возникает ошибка:

пробовал собирать с -fPIC (CFLAGS), с --with-pic, с --disable-static, с --enable-shared, со всеми вместе — всё равно та же ошибка.
помоги пожалуйста разобраться почему ошибка. надо ли собирать 32-битное что-то кроме glibc? надо ли x32?
