Froyo Build - 64-bit SO is preferred

I found this post on google groups.


Build Error during Make
Where Jean-Baptiste M. "JBQ" Queru said:

Java6 is not available in 32-bit on all platforms. 
Given that all of Google's development and testing happens on builds
created on 64-bit machines, there's some level of risk in letting
device manufacturers use 32-bit environments as we don't know what
happens in those cases. Java6 allows us to standardize on 64-bit and
eliminate that risk. 

And I found an Issue that is exactly mine (10 hours ago).
Android Build issue with Ubuntu 10.04

I can't wait the answer I switch to 64 environment.
