From: Andrew Pinski <apin...@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.
