Fix ALIGN_WITH_INPUT

ld/

2014-02-02  Sebastian Huber  <sebastian.huber@embedded-brains.de>

	* ld/ld.texinfo: Change ALIGN_WITH_INPUT documentation.
	* ld/ldlang.c (lang_size_sections_1): Add dotdelta
	variable which reflects the VMA change due to alignment
	requirements.  Use dotdelta do change the LMA if
	ALIGN_WITH_INPUT is requested.
