[yocto] Cannot create symlink to 'x86_64-pokysdk-linux' error

[Takashi Matsuzawa]

Hello yocto.
I have been successfully building several yocto based target trees,
but now trying qemux86-64 build and it is causing error.  Familiar
with the below sympthom and maybe you have any suggestion?

I think this begain happening when I did -c populate_sdk, but not sure.
The other targets (including qemux86) is building fine.  I am now
re-building it again after removing downloads, sstate-cache, tmp, etc.

I think this is copying files using tar as follows, and in the
copeid-to directory there is already 'x86_64-pokysdk-linux' directory
whereas in copied-from directory it is a symbolic link.  Hence tar
fails.

(coppied-from)
${TMPDIR}/work/x86_64-nativesdk-pokysdk-linux/nativesdk-libgcc/5.2.0-r0/sysroot-destdir
x86_64-poky-linux -> x86_64-pokysdk-linux (symlink)
x86_64-pokysdk-linux (directory)

=>

(copied-to)
${TMPDIR}/sysroots/x86_64-nativesdk-pokysdk-linux
x86_64-poky-linux (directory)
x86_64-pokysdk-linux (directory)
