GCC Android交叉编译libgcc crtbegin_so.o crtend_so.o错误

Question

我试图从Ubuntu 20.04 LTS（Focal Fossa）机器上为目标arm-linux-androideabi构建一个GCC交叉编译器。

GCC版本9.3.0。 Source

构建机器源

lsb_release -a

输出

Distributor ID: Ubuntu
Description:    Ubuntu 20.04 LTS
Release:    20.04
Codename:   focal

lscpu

输出（我认为这很有用）

一切顺利，一切都建立起来

从build-gcc目录make all-target-libgcc

或从build-gcc / arm-linux-androideabi / libgcc目录make all

或从build-gcc / arm-linux-androideabi / armv7-a / libgcc目录make all
