--target + nextest-archive cause llvm-cov to not find files

[cwfitzgerald]

When I use --target when building the initial archive, trying to run the archive cause llvm-cov to not find the files generated.

Generation command

cargo llvm-cov nextest-archive --all-features  --target aarch64-apple-darwin --archive-file tests.tar.zst

Error

$ cargo llvm-cov nextest --archive-file tests.tar.zst --extract-overwrite --no-fail-fast

warning: not found object files (searched directories: /Users/cwfitzgerald/programming/wgpu/target/llvm-cov-target/target/debug); this may occur if show-env subcommand is used incorrectly (see docs or other warnings), or unsupported commands such as nextest archive are used
No filenames specified!

The same problem happens with --no-report on the command, then calling cargo llvm-cov report --lcov --output-path lcov.info

I tried adding --target to the nextest call, but nextest doesn't except that argument with an archive file. Using --no-report and specifying the target when generating the report also doesn't work.

Motivation

Cross compiling from an x86 mac to generate archives used on an ARM mac. See gfx-rs/wgpu#5056

As always, I can PR things if you point me in the right direction.

This and #333 have been fixed in 0.6.1. Thanks for reporting these issues @cwfitzgerald!

(This case is now tested in CI)

cargo-llvm-cov/.github/workflows/ci.yml

Lines 90 to 92 in bab7732

	host=$(rustc -Vv | grep host | sed 's/host: //')
	cargo llvm-cov nextest-archive --archive-file a.tar.zst --target "${host}"
	cargo llvm-cov nextest --archive-file a.tar.zst --text --fail-under-lines 70 --target "${host}"

Amazing! Thanks for the super fast response and release!
