[PATCH] Remove `netbsdpe` support

[Nick Clifton]

Hi John,

   Sorry, but the binutils policy is to first add a target
   to the obsolete list, and then once a release has been
   made, actually remove it.  So I have patched bfd/config.bfd
   for now and once the 2.37 branch is cut, I will remove
   the support all together.

Cheers
   Nick
