```

otherwise, it won't compile on musl or non-x86_64 targets (it'll fail to detect the target triplet). The nostrip_files bit is not entirely necssary but it'll prevent it from trying.

also, you should find if you can somehow split the build/install steps.

i'll leave the rest to other reviewers
