RFC: turning off cortex optimizations for nightlies?

[Denys Dmytriyenko]

All,

I'm considering turning off cortex optimizations for nightly CoreSDK builds. 
Currently I'm building 8 machines and besides some machine-specific packages, 
most of the packages get duplicated into cortex-a8, cortex-a9 and cortex-a15 
arch-specific directories - each is about 1.5 GB.

Disabling cortex optimization will of course drop performance slightly (few 
percent, if I remember correctly), but besides size savings, it also saves on 
time for rebuilding those packages 3 times. All of them will be designated as 
armv7a and built once.

Any concerns, comments?

BTW, I was told not to disable optimization for now.
