pruneLibtoolFiles: init setup hook (#41819)
A .la file specifies linker flags to link with the library it describes. Its "dependency_libs" field lists the libraries that this library depends upon. This list often contains "-l" flags without corresponding "-L" flags. Many packages in Nixpkgs deal with this in one of these ways: - delete .la file [1] - clear dependency_libs [2] - add -L flags to dependency_libs [3] - propagate dependencies [4] Sometimes "dependency_libs" contain wrong "-L" flags pointing to the "dev" output with headers rather than to the main output with libraries. They have to be edited or deleted to reduce closure size [5]. Deleting .la files is often but not always safe [6]. Atomatically deleting as many of them as possible is complex [7]. Deleting .la files that describe shared rather than static libraries is probably safe; but clearing their "dependency_libs" field achieves the same effect with less potential for unintended consequences. This is the approach that may be enabled for all Nixpkgs.
