ARM build fails in libgloss: no redboot.ld

Okay. I see it -- libgloss couldn't figure out that this was an elf
target. I updated the appropriate part of the libgloss/arm
and things are now building.

I remain a bit confused about the theory of operation for libgloss. It
appears to me that libgloss is intended to provide "bare" board support.
This raises two (naive, apologies) questions:

  1. When an OS is present, should libgloss be disabled? How?
  2. Given that an OS is not present, I would still expect libgloss
     to be board specific, but it does not appear to have a BSP

While I'm thinking about it, how should own specify a configure "triple"
when one intends to specify a specific target BSP to be built? For
example, assuming I have made the appropriate configure file changes, if
what I want is

	OS = coyotos
	ARCH = arm
	VENDOR = erosgroup
	BSP = coolboard

how should this be expressed in the --target argument to configure?
