Breakage of GHC (linker misses `gmp`) on ubuntu-24.04 20250527.1.0 image

[andreasabel]

Is this something that can be fixed in the Alpine setup?

• ubuntu-24.04 20250527.1.0 broke building Haskell project under alpine actions/runner-images#12324
• Workflow deploy: install libgmp agda/agda#7919

Basically, with GHA upgrading their image to 20250527.1.0 compilation with GHC under Alpine breaks in the linking phase, not finding the gmp library.
But afaics, the gmp library is a dependency of ghc in Alpine...
