build fails on 2.0.3

[tzachar]

the following line fails on rust 1.81:

croaring-rs/croaring-sys/build.rs

Line 11 in f75467c

build.flag_if_supported(format!("-march={target_arch}"));

there should be a '&' before the format!:

build.flag_if_supported(&format!("-march={target_arch}"));

[Dr-Emann]

The problem is that build.flag_if_supported was changed to support owned and borrowed strings in cc version 1.1, but coraring-sys incorrectly claimed it only needed at least cc version 1.0. You should be able to cargo update your cc version to something > 1.1, or the newest croaring-sys (published today) now correctly identifies the minimal cc version it requires.

See #149, which updated the minimal cc version, but today is the first croaring-sys publish since that change.

10x.
Did a cargo update, which solved the issue.
