This fixes a problem for 64-bit Cygwin, where building some packages can

produce spurious errors about truncated relocations.  The relocations are
only truncated because they are being made against sections which are going
to be discarded so that base address is zero instead of the expected 64-bit
base value.

	* cofflink.c (_bfd_coff_generic_relocate_section): Skip
	relocations in discarded sections.
