Missing symbols file in libc6 for loong64

Hi, Adrian

I noticed that many binary packages on loong64 have a dependency to =
libc6 with
a version constraint no lower than the latest version of glibc, which is
different from other architectures, where the version constraint is =
derived
from the actual symbol version sused in the executables. I believe that =
it is
because of missing symbols file in libc6 for loong64.

I have opened a merge request to glibc packaging adding the missing =
symbols
file and the merge request has been merged and is pending for upload. I =
wonder
what should be done to existing packages which requires a unnecessary =
higher
version of libc6.

Cheers,
