For ghc Version 9.4.7, we have added loongarch support and built the
unreleased version 9.4.7+loong64.
The ghc Version 9.4.7+loong64 was uploaded to pool-loong64 repository on
Nov, 2023.
I installed ghc 9.4.7+loong64 on my local ENV, the result of run 'ghc
--info' is as follows,
```
root@localhost:/home# ghc --info
[("Project name","The Glorious Glasgow Haskell Compilation System")
,("GCC extra via C opts","")
,("C compiler command","loongarch64-linux-gnu-gcc")
,("C compiler flags","")
,("C++ compiler command","loongarch64-linux-gnu-g++")
,("C++ compiler flags","")
,("C compiler link flags","-fuse-ld=bfd")
......
```

Thanks for your help, sincerely.
But I'd like to note that the latest ghc version in the experimental
repository is currently 9.6.5-1~exp1.
Please see
https://buildd.debian.org/status/package.php?p=ghc&suite=experimental.
As you said, we really should submit bugs and make patch based on ghc
9.6.5-1~exp1.
Based on ghc 9.6.5-1~exp1, I have added extra --ghc-options in d/rules
for loong64.
Please consider the patch I attached.
Your opinions are welcome.
Thanks,
Dandan Zhang
