Add back unwinding support for Sony PSP

This PR adds back unwinding support for the Sony PSP. The `mipsel-sony-psp` target works well with unwinding. In [rust-psp], we use the `panic_unwind` crate along with LLVM's libunwind to catch panics, run destructors, and print them to the debug screen without aborting all threads.
