Since ar and ranlib don't need to know symbol types to work properly,
we should avoid calling lto-wrapper for them to speed them up.

bfd/

	PR binutils/25584
	* plugin.c (need_lto_wrapper_p): New.
	(bfd_plugin_set_program_name): Add an int argument to set
	need_lto_wrapper_p.
	(get_lto_wrapper): Return FALSE if need_lto_wrapper_p isn't
	set.
	* plugin.h (bfd_plugin_set_program_name): Add an int argument.

binutils/

	PR binutils/25584
	* ar.c (main): Pass 0 to bfd_plugin_set_program_name.
	* nm.c (main): Pass 1 to bfd_plugin_set_program_name.

Nick, Alan, is this patch OK for master?

Nick, is this patch OK for backport to 2.34 branch?

Thanks.

Looks OK to me for both master and 2.34.
