Subject: [PATCH] Disable libunwind for RTEMS OS (rust-lang/backtrace-rs#665)

We added target support for RTEMS OS in https://github.com/rust-lang/rust/pull/127021

It has a POSIX interface, so we could reuse much of the `unix` backend, but
currently libunwind is not supported.

Add a `cfg` switch to disable libunwind for RTEMS.
