objtool: Skip unreachable warnings for GCC 4.4 and older
The kbuild bot occasionally reports warnings like:
drivers/scsi/pcmcia/aha152x_core.o: warning: objtool: seldo_run()+0x130: unreachable instruction
These warnings are always with GCC 4.4. That version of GCC sometimes
places unreachable instructions after calls to noreturn functions.
The unreachable warnings aren't very important anyway. Just ignore them
for old versions of GCC.
