haskell: add combinator to enable DWARF debuggingorigin/haskell-dwarf-debugging
Tested using:
$ cat test-strip.nix
with (import ./. {});
with haskell.lib;
haskell.packages.ghc802.override {
overrides = self: super: {
microlens = enableDWARFDebugging super.microlens;
};
}
$ nix-build -A microlens test-strip.nix
$ objdump -t <path-to-so-file>
