Commit Message

Li, Pan2 via Gcc-patches Sept. 18, 2021, 1:21 a.m. UTC 
From: Andrew Pinski <apinski@marvell.com>

So the problem here is that now the lto-plugin requires NM that works
with LTO to work so we need to pass down NM just like we do for ranlib
and ar.

OK? Bootstrapped and tested with --with-build-config=bootstrap-lto on aarch64-linux-gnu.
Note you need to use binutils 2.35 or later too due to ttps://sourceware.org/PR25355
(I will submit another patch to improve the installation instructions too).

config/ChangeLog:

	PR bootstrap/102389
	* bootstrap-lto-lean.mk: Handle NM like RANLIB AND AR.
	* bootstrap-lto.mk: Likewise.
