objtool: Disable GCC '-Wpacked' warnings
Objtool is failing to build with GCC 4.4.7 due to the following
warnings:
cc1: warnings being treated as errors
In file included from orc.h:21,
from orc_gen.c:21:
orc_types.h:86: error: packed attribute is unnecessary for ‘sp_offset’
orc_types.h:87: error: packed attribute is unnecessary for ‘bp_offset’
orc_types.h:88: error: packed attribute is unnecessary for ‘sp_reg’
I suspect those warnings are a GCC bug. But -Wpacked isn't very useful
anyway, so just disable it.
