We've updated the "reproduce" section in bot's reports to be more
precise. Thanks a lot for the inputs.

Please follow below steps to use the toolchains provided by kernel.org.
We've tested this and it can work in a debian 11.6 docker env.
$ cat /etc/debian_version
11.6
$ ldd -v /lib/x86_64-linux-gnu/libc.so.6 | grep GLIBC
ld-linux-x86-64.so.2 (GLIBC_2.3) => /lib64/ld-linux-x86-64.so.2
ld-linux-x86-64.so.2 (GLIBC_PRIVATE) => /lib64/ld-linux-x86-64.so.2
$ export URL=https://mirrors.edge.kernel.org/pub/tools/crosstool/files/bin/x86_64
$ COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-12.1.0 ./make.cross W=1 ARCH=csky olddefconfig
Compiler will be installed in /root/0day
lftpget -c https://mirrors.edge.kernel.org/pub/tools/crosstool/files/bin/x86_64/./12.1.0/x86_64-gcc-12.1.0-nolibc-csky-linux.tar.xz
/root/linux
tar Jxf /root/0day/12.1.0/x86_64-gcc-12.1.0-nolibc-csky-linux.tar.xz -C /root/0day
make --keep-going CONFIG_OF_ALL_DTBS=y CONFIG_DTC=y CROSS_COMPILE=/root/0day/gcc-12.1.0-nolibc/csky-linux/bin/csky-linux- --jobs=144 W=1 ARCH=csky olddefconfig
...
Thanks a lot for the suggestions. We will further improve the 0day
make.cross tool such as:
* Provide statically linked toolchains that don't depend on the libc in
the distribution
* Add hint to help user decide whether to use 0day or kernel.org
toolchains.
