Provide the proper override macros for x32 siginfo_t. The combination of a special type here and an overall alignment constraint actually ends up with all the types being properly aligned, but the hack is needed to keep the substructures inside siginfo_t from adding padding. Note: use __attribute__((aligned())) since __aligned() is not exported to user space. [ v2: fix stray semicolon ] Reported-by: H.J. Lu <hjl.rools@gmail.com> Cc: Bruce J.
