However, AIX structures don't provide such names and must be modified.

TODO(aix): create a script to automatise defs_aix creation.

Modifications made:
 - sigset replaced by a [4]uint64 array
 - add sigset_all variable
 - siginfo.si_addr uintptr instead of *byte
 - add (*timeval) set_usec
 - stackt.ss_sp uintptr instead of *byte
 - stackt.ss_size uintptr instead of uint64
 - sigcontext.sc_jmpbuf context64 instead of jumbuf
