Thanks!
I'll stamp this without particular scrutiny on the basis that:
- Only the PSP target is affected by this commit.
- PSP is a Tier 3 target so whatever happens happens.
- You are the maintainer of rust-psp which is a real project with a large number of stars. Consequently if you say it works that's enough for me!

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