* scripttempl/elfppc.sc: Correct .rela.sdata entries.

	* scripttempl/elfppc.sc: Put the PLT between the small and large
	BSS segments.
	* emulparams/elf32ppc.sh (TEXT_START_ADDR): The ABI says `A
	program base of 0x02000000 is recommended...' because otherwise
	shared libraries are less efficient.  We use 0x01800000 because
	otherwise it's impossible to branch to location 0, for instance if
	you have an undefined weak symbol.
