Nick Clifton 925bbbbb98 * scripttempl/elf32msp430.sc (.data): Set the based on the next
free location in the text memory region, not a computation based
	upon the size of the text section.  Orphaned sections or other
	linker scripts might insert new sections between the .text section
	and the .data section.
	* scripttempl/elf32msp430_3.sc (.data): Likewise.
