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

[James Bottomley <James.Bottomley@SteelEye.com>]

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.
