Fix ridiculous pc offsets for static symbols in .so files.

Example before:

  static	art::HandleUnexpectedSignal(int, siginfo*, void*)+4146013245 [0xf75f6fcd] (libartd.so)

...and after:

  static 	art::HandleUnexpectedSignal(int, siginfo*, void*)+1085 [0xf7e9872d] (libartd.so)

(This matches what gdb's x/1i said.)
