- For the compilation error raised by Matthias Klose.
It is because the linux header file linux-libc-dev lacks loong64 support.
The Debian kernel-team has merged the loong64's patch, please see
https://salsa.debian.org/kernel-team/linux/-/merge_requests/879.
- I have reproduced the gcc-14 compilation error locally from Adrian Bunk.
The compilation error is consistent with the feedback from Adrian Bunk.
For gcc-14, the loong64's multilib modification is not included in
gcc-multilib-multiarch.
Please consider the following patch. If you have any questions, you can
contact me at any time.

BTW, the gcc-14 source package was compiled successfully on my local
loong64 rootfs environment, for examples,
