Rollup merge of rust-lang#130781 - monkeydbobo:mdb/fix_up_cross_compile_osx, r=davidtwco

Fix up setting strip = true in Cargo.toml makes build scripts fail in…

Fix issue: rust-lang#110536
Strip binary is PATH dependent which breaks builds in MacOS.
For example, on my Mac, the output of 'which strip' is '/opt/homebrew/opt/binutils/bin/strip', which leads to incorrect 'strip' results. Therefore, just like on other systems, it is also necessary to specify 'stripcmd' on macOS. However, it seems that there is a bug in binutils [bugzilla-Bug 31571](https://sourceware.org/bugzilla/show_bug.cgi?id=31571), which leads to the problem mentioned above.
