Expand report code size reporting?

[aolofsson]

Would this be possible?

-Build and report code size for ARM, x86, Epiphany
-Would require developers to install ARM and Epihany tool chain dependencies.

Some of the current contributions are too x86 centric, this might help bring everyone done by one level?

Some CSS and this will look decent

Only dependencies gawk and sqlite3

Hope to have it cleaned up tomorrow.
