`--enable-deterministic-archives` is a GNU specific strip flag and causes other strip implementations (for example LLVM's, see #138013) to fail. Since strip failures are ignored, this means that stripping doesn't work at all in certain situation (causing unnecessary dependencies etc.). To fix this, no longer pass `--enable-deterministic-archives` unconditionally, but instead add it in a GNU binutils specific strip wrapper only. `commonStripFlags` was only used for this flag, so we can remove it altogether. Future work could be to make a generic strip wrapper, with support for nix-support/strip-flags-{before,after} and NIX_STRIP_FLAGS_{BEFORE,AFTER}. This possibly overkill and unnecessary though -- also with the additional challenge of incorporating the darwin strip wrapper somehow.
