Thanks Alan, is it possible for binutils to have different plugin
enabling for sub-programs?  we use below configuration options, from
which I see nothing special.

.../binutils-gdb/configure
--enable-64-bit-bfd
--enable-targets=arm-none-eabi,aarch64-none-linux-gnu,aarch64-none-elf
--disable-newlib-supplied-syscalls
--enable-newlib-io-long-long
--enable-newlib-mb
--disable-gdb
--without-gdb
--target=aarch64-none-elf
--prefix=...
--with-pkgversion=unknown
--disable-nls
--without-x
--disable-gdbtk
--disable-tui
--without-python
--without-tcl
--without-tk

Thanks,
bin
