Building on Ubuntu AMD64 bit enviroment

[ubuntu_user]

Hi All,
I am wondering if anyone has successfully rebuild the open source on a
Linux 64 bit enviroment. I already install all 32 bit lib for my GCC
and I still get these errors:

build/core/product_config.mk:229: WARNING: adding test OTA key

You need to install the package g++-multilib for this particular error.
