[PATCH] fix git-checkout-cache segfault on parisc

This one I think is Linus' fault, so send him a brown paper bag with my complements ...

The index cleanup code is executed via atexit() which is *after* main has completed, so the stack allocated cache_file has gone out of scope. Parisc seems to use stack in the destructor functions, so cache_file gets partially overwritten leading to the predictable disastrous consequences.
