Dear maintainers,
The package ceph failed to compile on loong64 in the Debian Package
Auto-Building environment. The error messages are as follows,
```
/usr/bin/ld: /usr/include/c++/13/bits/atomic_base.h:1015:(.text+0x9dc):
undefined reference to `__atomic_compare_exchange_16'
/usr/bin/ld: /usr/include/c++/13/bits/atomic_base.h:1015:(.text+0xa00):

cd /<<PKGBUILDDIR>>/obj-loongarch64-linux-gnu/src/librbd &&

```
The full compilation log can be found at
https://buildd.debian.org/status/logs.php?pkg=ceph&ver=16.2.11%2Bds-5&arch=loong64
BTW, ceph upstream uses the "__SIZEOF_INT128__" macro definitions
starting with version v18.0.0, please see details at
https://github.com/ceph/ceph/blob/v18.0.0/cmake/modules/CheckCxxAtomic.cmake.
Environment information for loong64 rootfs:
root@localhost:/home/ceph# dpkg-architecture |grep DEB_HOST_ARCH_CPU
DEB_HOST_ARCH_CPU=loong64
root@localhost:/home/ceph# gcc -dM -E - </dev/null |grep __SIZEOF_INT128__
#define __SIZEOF_INT128__ 16
For the ceph version in the debian sid, please consider the patch I have
attached.
If you have any questions, you can contact me at any time.
thanks,
