Remove obsolete support for linking unwinder on Android

pcc · pcc · commit d44975813540 · 2023-11-02T17:50:43.000-07:00
Linking libgcc is no longer supported (see #103673), so remove the related link attributes and the check in unwind's build.rs. The check was the last remaining significant piece of logic in build.rs, so remove build.rs as well.
