[PATCH] relocatable kernel: Fix kallsyms on avr32 after relocatable kernel changes

o On some platforms like avr32, section init comes before .text and
  not necessarily a symbol's relative position w.r.t _text is positive.
  In such cases assembler detects the overflow and emits warning. This
  patch fixes it.
