Hi,

Trying to apply Sedat's patch something changed in my system,
and that patch wasn't enough, so I had to first apply this one:

commit 173b552663419f40bcd3cf9df4f68285cac72727
Author: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>
Date: Mon Apr 4 17:28:48 2022 -0300

tools build: Use $(shell ) instead of `` to get embedded libperl's ccopts

Just like its done for ldopts and for both in tools/perf/Makefile.config.

Using `` to initialize PERL_EMBED_CCOPTS somehow precludes using:

$(filter-out SOMETHING_TO_FILTER,$(PERL_EMBED_CCOPTS))

And we need to do it to allow for building with versions of clang where
some gcc options selected by distros are not available.

After this I go on filtering out some of the gcc options that clang
doesn't grok:

And then get to the problems at the end of this message, which seem
similar to the problem described here:

>From Nathan Chancellor <>
Subject [PATCH] mwifiex: Remove unnecessary braces from HostCmd_SET_SEQ_NO_BSS_INFO

https://lkml.org/lkml/2020/9/1/135

So perhaps in this case its better to disable that
-Werror,-Wcompound-token-split-by-macro when building with clang?
