binutils-gdb/ld/ldtemplate
Per Bothner b7e24eef35 * news.sc: Add alignment for data segment.
* ldtemplate: Add (yet another) script to get for -n or -N
	options.  (These need different alignment than ZMAGIC files.)
	* Makefile.in:  Add stuff for new foo.xn scripts.
	These are generated by replacing "ALIGN(0x...00)" by ".".
