[RFC v0 0/1] Add support for CRC64 generation in linker

[binutils@emagii.com]

Cleaned up attempt to generate CRC64.


Added code in lang_end() to calculate the CRC.
So far, I can retrieve the location of the CRC
and the start and end for the area.
I can fetch the .text segment as an asection but
 
  if ( bfd_get_section_contents (link_info.output_bfd,
	  ts,
	  text_section,
	  0,
	  ts->size))

fails...

The patchset should contain the LICENSE and the testsuite
but git-send-email does not like if I send 8 patches.
Sending 6 patches is OK for some reason...
