Thanks to Myles' patch adding support for include statements,

refactoring Config.lb became possible.

Factor out ROM size calculation from Config.lb.
  
This patch converts 87 boards (with and without USE_FAILOVER_IMAGE),
but it has to work around a parser bug. 

89 files changed, 209 insertions(+), 2415 deletions(-)
A total of 2206 removed lines.
  
Abuild works for all changed boards on khepri.

Myles writes:
I've tested serengeti for the failover portion and s2892 for the
nofailover portion.  ldoptions are exactly the same and they both boot
the same.
