[PATCH] merge.c fix

[Jakub Jelinek]

Hi!

I've commited the following patch. _bfd_merged_section_offset could access
a byte before secinfo->contents and segfault if secinfo->contents pointed
at start of an mmap area before figuring out it is at start of section.

	* merge.c (_bfd_merged_section_offset): Avoid accessing byte before
	section content start.
