Hard-coded `strip` path breaks Linux -> Darwin builds

[rvolosatovs]

I cross-compile code for Darwin from Linux, which now fails due to the strip path being hard-coded in latest nightly, which I believe is caused by this PR #130781

I expected to see this happen: successful compilation

Instead, this happened:

error: unable to run `/usr/bin/strip`: No such file or directory (os error 2)

https://github.com/rvolosatovs/nixify/actions/runs/11163623704/job/31031050404?pr=265

I'm not sure why /usr/bin/strip was chosen as the strip to use, as an end user - that is surprising, in fact I would have expected the strip from the environment to be used by default. If the intention is to set a default to a hardcoded path, then it looks like a configuration option must be provided.

Alternatively, perhaps cargo could use /usr/bin/strip if found and otherwise use strip from environment?

Version it worked on

It most recently worked on: 1.80.1

Version with regression

rustc --version --verbose:

cargo 1.83.0-nightly (80d82ca22 2024-09-27)

(The results are not exactly the same, but things are broken for the same cause.)

@taiki-e no, that's a different issue, since strip does work fine on Linux to strip Darwin binaries. The issue here is the hardcoded path introduced a week ago

Oh, sorry, I missed the information that that used to work.

(In any case, I think the correct solution to these problems is the same one: #123151)

indeed, LLVM strip works great for my use case, on current nightly, however, there is no way to make sure it's used other than explicitly putting the binary in /usr/bin/strip.

Will #123151 land before 1.83? I don't think #130781 should land in a release and seems that it currently targets 1.83

Not sure how to solve the strip situation...
