[U-Boot] [RFC/PATCH] Makefile: allow boards to check file size limits

[Vaibhav Bedia]

Hi,

The size of other sections like the bss section also need to be accounted
for when doing a size check.

Insufficient space for bss when doing something like a MMC read which
requires large buffers causes system hangs for no apparent reason.
