elf32-arm.c (elf32_arm_gc_sweep_hook): Don't reinitialize pp to avoid null
pointer dereference.

I think that I found the cause of the bug. Bisecting the git repository showed
that commit 740e291 (http://bit.ly/mA8nk7) introcuded it. Clearly the
initialization in for() loop at line 12041 should go away to avoid null pointer
dereference, as happened here.
