Allocate the main program stacks after the loaded program.
...
After we relocate the program, we restart it. So there is no need to copy
over the old stack contents. This allows us to increase the maximum number
of APs without a run time overhead. The maximum number of APs will still
be limited by the size of low memory.

Rearrange stack space to reduce memory footprint.
...
The BSP only needs extra stack space during program initialisation. The APs
aren't running at that point, so by positioning the BSP stack above the AP
stacks, it can extend down into the AP stack space without causing any
problems.

Use 'size -B' instead of 'size -G' to determine BSS size.
...
The -G option is a relatively recent addition, so fails on older
systems (issue #11 ).
