为ARM64编译binutils-2.33.1（aarch64 *--。]
构建通过，但是在某些程序中我遇到了奇怪的问题。例如，GNU MP在构建其生成器时会进行核心转储。处理long的问题似乎已中断。
当我在binutils-2.33.1构建上运行make check时。只有3个意外故障。他们绝对脱颖而出：
Running /custom_toolchain/binutils-2.33.1/binutils/testsuite/binutils-all/aarch64/aarch64.exp ...
FAIL: Check if disassembler can handle all sections in default order
FAIL: Check if disassembler can handle all sections in different order than header
Running /custom_toolchain/binutils-2.33.1/binutils/testsuite/binutils-all/objdump.exp ...
Version /custom_toolchain/build/binutils/objdump 2.33.1
FAIL: build-id-debuglink (grepping for source file name in disassembly output)
我可以安全地忽略这些失败吗？如果没有，对原因有任何想法吗？
您不应忽略这些失败。如果可以访问linux x86_64系统，则可以使用可以信任的工具链交叉编译binutils 2.33.1，例如来自Linaro或Arm的gcc工具链：根本原因可能是有缺陷的工具在您的Aarch64系统上。
在Linux x86_64系统上交叉编译binutils的过程为：

然后，您可以将复制的binutils可执行文件替换到目标系统中：如果您的问题与binutils相关，则可以很好地解决它。
