[Patch] Convert PE relocatable modules to ELF with objcopy

objcopy from binutils-20060817-1 cannot convert pe-i396 to elf32-i386. 
The offsets of the pc-relative relocation entries are not converted 

I recently started a Cygwin port of GRUB2 ([Maybe ITP later]-).

GRUB2 loadable modules use ELF format, therefore, some PE to ELF 
conversion is required to build on Cygwin.

The first working Cygwin patch for GRUB2 includes a workaround to load 
the broken ELF modules produced by objcopy. It would be desirable to fix 
this in objcopy itself.

A patch is attached.

	* objcopy.c (fix_relocation): New function to
	fix pc-relative relocation offset, for PE to ELF only.
	(copy_section): Call fix_relocation for	section data.
