Switch to using a shared main() for all of the embedded BSPs
based on the GNU tools. This usually involved correcting the
type of bsp_start(), bsp_cleanup(), adjusting the start code to
call the right start routine (the shared boot_card()), and then
removing code from bsp_start() which was performed in the new
boot_card()/main() path.

| 2 | * A simple main which can be used on any embedded target. |
---|
| 3 | * |
---|
| 4 | * This style of initialization insures that the C++ global |
---|
| 5 | * constructors are executed after RTEMS is initialized. |
