include dbxelf.h elfos.h freebsd-spec.h rs6000/sysv4.h netbsd.h

and netbsd-elf.h on powerpc64-netbsd.

port netbsd64.h forward from GCC changes.  (it's a pity that
a vast portion of linux64.h isn't in some common header that
netbsd64.h and freebsd64.h could also used.  there's 100s of
lines of copypasta here, oh well.)
