PR 356/bsps
	* bsp_specs, start/Makefile.am, startup/linkcmds
	This patch makes RTEMS/powerpc/shared EABI compliant.
	Declare all linker-script defined addresses as
	variables of unknown size and not as short objects
	like 'int', 'void*' etc.
	This prevents the compiler from generating a relocation
	who assumes the existence of an __rtems_end object in
	one of the short data areas (which would result in a
	linker error).
