Subject: [PATCH 21/31] gnu: ghc-lua: Disable symbol export.
Date: Sat, 11 Feb 2023 11:08:15 +0100

This turns on the linker flag -Wl,-E for all libraries depending on it,
resulting in large binaries, because --gc-sections cannot clean exported
symbols.

* gnu/packages/haskell-xyz.scm (ghc-lua)[arguments]: Disable
export-dynamic feature.
