This is a hard file to replace outside the tree because the bsp_specs
reference it.

I have used a hack in the past where I call a single C routine
from the start.S (boot_card) and I provide that routine myself.
It can do minimal initialization of a serial port and push a few 
characters out.

I only do this when starting a BSP.  For other mods, I build
usually enable maintainer mode and build from the top.  If
I have compile problems on a single file, I go down to that directory
in the build tree to do makes.
