[yocto] Cannot run simple binary executable file

[Wy kevinthesun]

However, a new problem occurs. Now when I tries run HelloWorld binary,
after "Hello World" is printed, the terminal also prints "Segmentation
fault". It seems that some memory problems occurs. I guess it comes from
that the 1.5.1 yocto system on boards hopes ld-linux-armhf.so.3 as dynamic
linker, instead of ld-linux.so.3, which is used by toolchain. There may be
some memory address problem between them. How can I solve it?

Thank you!
