This part I'm not clear on.  I found this in gdb/configure.ac:

# We only build gdbserver automatically in a native configuration.
if test "$gdb_native" = "yes"; then
  AC_MSG_CHECKING(whether gdbserver is supported on this host)
  if test "x$build_gdbserver" = xyes; then
    AC_MSG_RESULT(yes)
    AC_CONFIG_SUBDIRS(gdbserver)
  else
    AC_MSG_RESULT(no)
  fi
fi

I couldn't find any docs on building gdbserver for cross targets (i.e
--host != --target), got any pointers?  It's only useful for targets
that otherwise can be build natively (AIUIp.  Would gdbserver ever be
built with CC_FOR_TARGET whereas gdb got built with CC?  I can't find
any code to handle this in gdb or the top level configury.  And if not
would gdbserver ever need a different libiberty than the one gdb is
linked with?
