Hi Masahiro,
For a long time I have been using GNUmakefile in the top level source directory to change compilers, enable ccache etc. Here's a simplified GNUmakefile example:
CROSS_COMPILE=/opt/cross/gcc-13.1.0-nolibc/x86_64-linux/bin/x86_64-linux- include Makefile
This was working fine on v6.4. But I noticed that it got broken on v6.5-rc1 and the host compiler is used instead of what I have specified in CROSS_COMPILE variable. It looks like GNUmakefile is ignored.
I did a bisect and found the commit which broke this:
commit 5fc10e76fa2a96d0207ed4d0cc9d16fb61371f71 Author: Masahiro Yamada <masahiroy@kernel.org> AuthorDate: Tue Jun 27 08:30:13 2023 +0900 Commit: Masahiro Yamada <masahiroy@kernel.org> CommitDate: Wed Jun 28 01:35:02 2023 +0900
kbuild: revive "Entering directory" for Make >= 4.4.1
Reverting this commit fixes the issue and GNUmakefile works again as before. I'm using Debian 12 on x86 with GNU Make 4.3-4.1:amd64. Here's the bisect log:
