Patch to replace BFD_NEED_DECLARATION with AC_CHECK_DECLS

[Steve Ellcey <sje@cup.hp.com>]

This patch removes the use of BFD_NEED_DECLARATION from gdb/gdbserver
and replaces it with AC_CHECK_DECLS.  Once this checkin is done I intend
to remove the definition of BFD_NEED_DECLARATION from the bfd
subdirectory as it is no longer needed now that we are using newer
versions of autoconf that have AC_CHECK_DECLS.

There is still a use of BFD_NEED_DECLARATION in src/mmalloc but my
understanding is that mmalloc is no longer used and so that use can be
ignored.

The change was tested on IA64 Linux with no regressions.  I have not
done any gdb checkins before but I have done binutils changes and I do
have a gdb copyright assignment on file and write access to the src
repository so I can check this in myself if it is approved.

OK to checkin?
