I think you are going to have to give us more information.

1) Is this 'core2-64-poky-linux' a reference to this?:
https://www.yoctoproject.org/tools-resources/projects/poky

2) Are you trying to cross-compile for another platform?

3) Can you explain what is going on here?:

build/tmp/sysroots/qemux86-64/usr/lib/../lib/Scrt1.o: In function `_start':

build/tmp/work/core2-64-poky-linux/glibc/2.22-r0/git/csu/../sysdeps/x86_64/start.S:104:
undefined reference to `main'
