[ale] Use cloud guest to compile kernel

[Chris Fowler]

Is this a bad idea? 

I need to compile a 4.7.2 kernel for i586. The kernel config is copied from debian jessie with CONFIG_M586TSC=y. 

I don't have 2 days to wait. 

1. Spin up a CentOS 6.X 32 bit guest at Digital Ocean with 8 cores and 16GB of ram. This is $0.25/ht 
2. Transfer linux-4.7.2.tar.xz and the config to it. 
3. Unpack, copy the config to .config, make, create package, and transfer back to the i586 hardware. 
4. Delete the guest. I only pay for the usage. 

I'm doing this on a Digital Ocean guest of lowest power. Only 0.007/hr. It is still taking a long time. 
I need to build the same kernel, but for i586, i686, and x86_64. I have the configs ready to go. I'm also perfecting my packaging too so I may have to build a few times. 

I making assumptions based on my assumption that I can use 8 cores at 100% each for a couple hours. With Azure I can pay for a quarter core for testing under Winders.
