Sedat Dilek noticed duplicated debug flags passed when building C
files with CONFIG_DEBUG_INFO.
I do not know much about his build environment, but yes, Kbuild
recurses to the top Makefile with some build targets. For example,
'make CC=clang bindeb-pkg' reproduces the issue.
With commit 121c5d08d53c ("kbuild: Only add -fno-var-tracking-assignments
for old GCC versions") applied, DEBUG_CFLAGS is now reset only when
CONFIG_CC_IS_GCC=y.
Fix it to reset DEBUG_CFLAGS also when using Clang.
Fixes: 121c5d08d53c ("kbuild: Only add -fno-var-tracking-assignments for old GCC versions")

Great, Masahiro!
I wanted to request an "undrunken" switch for GNU/make :-).

That fixes the issue for me:

With this patch:
... -Wno-unused-const-variable -g -gdwarf-5 -gz=zlib -pg -mfentry ...
The relevant Kconfigs:

Ah, OK.
You use bindeb-pkg for building the kernel.
That's why this happens only for you,
but Nick did not observe this issue.

Yes, this makes sense given that the original code, before commit
121c5d08d53c did always set DEBUG_CFLAGS without checking for
CONFIG_CC_IS_GCC. So it behaved like the above code does.
