Dear maintainers,

The haskell-pandoc-lua-engine is blocked from building by haskell-pandoc 
in the Debian Package Auto-Building environment.
Compiling the haskell-pandoc-lua-engine failed for loong64 in my local ENV.
The error message is consistent with haskel-pandoc, and both are related 
to "relocation R_LARCH_B26 overflow ......" during static linking in the 
test-pandoc stage.
The build error log of haskell-pandoc-lua-engine from my local ENV is as 
follows,
```
[6 of 6] Linking 
dist-ghc/build/test-pandoc-lua-engine/test-pandoc-lua-engine
/usr/bin/ld.bfd: 
/usr/lib/ghc/lib/../lib/loongarch64-linux-ghc-9.4.7/rts-1.0.2/libHSrts-1.0.2.a(NonMovingMark.o): 
relocation R_LARCH_B26 overflow 0xfffffffff61da41c
Dump relocate record:

...
0x0000000000000000 R_LARCH_B16    `.L172'
......
```

There are two suggestions to solve "relocation R_LARCH_B26 overflow 
......" during static linking.
1.Add build rules to reduce binary size.
2.Disable tests in d/rules on loong64.
The detailed information can be found from haskell-pandoc's Bug 
(#1069165) I just submitted.

It is recommended to use "DEB_ENABLE_TESTS = no" in d/rules for loong64.
Please consider the patch I attached.
With the attached patch, the haskell-pandoc-lua-engine was built 
successfully in my local ENV.
```

```

Your opinions are welcome.

Thanks,
