The patch by fanpeng already adds lld to debian/control for loong64:

--- a/debian/control
+++ b/debian/control
@@ -19,6 +19,8 @@ Build-Depends:
   hadrian:native (<< 9.10.4~) <!pkg.ghc.nohadrian>,
   llvm-21 (>= 1:21.1.6) [armel armhf s390x riscv64 loong64],

Your patch is not correct as it add "lld" as an unconditional build dependency to the ghc
package. However, lld is only available on a limited set of architectures rendering the
ghc package BD-Uninstallable on the architectures without lld support.
