Flags passed to the `strip` command applied to the files in the directories listed in `stripDebugList`. Defaults to `-S` (i.e. `--strip-debug`).
##### `stripExclude` {#var-stdenv-stripExclude}
A list of filenames or path patterns to avoid stripping. A file is excluded if its name _or_ path (from the derivation root) matches.
This example prevents all `*.rlib` files from being stripped:
```nix
stdenv.mkDerivation {
# ...
stripExclude = [ "*.rlib" ]
}
```
This example prevents files within certain paths from being stripped:
```nix
stdenv.mkDerivation {
# ...
stripExclude = [ "lib/modules/*/build/* ]
}
```
##### `dontPatchELF` {#var-stdenv-dontPatchELF}
If set, the `patchelf` command is not used to remove unnecessary `RPATH` entries. Only applies to Linux.
