Fix compile time warning in bfd/xsym.c

Fix compile time warning in bfd/xsym.c

[Nick Clifton]

Hi Guys,

  I am applying the patch below to fix a compile time warning building
  bfd/xsym.c.  The problem was a call to memcpy() with a size of 0.
  It was not exactly clear from the code if this was intentional or a
  coding bug, so I chose to assume that the code was correct.  This
  may need to be revisited one day.

Cheers
  Nick
