Auto merge of #10092 - ChrisDenton:tmp-match-err, r=alexcrichton

Match any error when failing to find executables

For Windows targets, Rust now uses [a custom resolver](rust-lang/rust#87704) to find `process::Command` programs. This has caused some error messages to change.

To allow the PR to be merged, some tests have been adjusted to match any error.
