[yocto] Fail to build core-image-minimal when MACHINE=genericx86-64

[Markus Svilans]

Hi Khem,

Per your suggestion, I installed gcc-multilib and was able to build 
syslinux and core-image-minimal. Wonderful!

Thank you for having a look at this problem and finding the fix.

May I suggest that the Ubuntu/Debian section in Yocto Quick Start 
documentation 
(https://www.yoctoproject.org/docs/current/yocto-project-qs/yocto-project-qs.html) 
be updated with this new information? Should I file a bug report to help 
this happen?

Best regards,
Markus
