gcc4: disable __compiletime_object_size for GCC 4.6+
__builtin_object_size is known to be broken on gcc 4.6+.
See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48880 for details.
This causes unnecssary build warnings and errors such as
In function 'copy_from_user', inlined from 'sb16_copy_from_user'
at sound/oss/sb_audio.c:878:22:
arch/x86/include/asm/uaccess_32.h:211:26: error: call to 'copy_from_user_overflow'
declared with attribute error: copy_from_user() buffer size is not provably correct
make[3]: [sound/oss/sb_audio.o] Error 1 (ignored)
Disable it where broken.
