I looked again and saw that the existing architectures also #undef __SYSCALL,
and they don't have __SC_WRAP. It's probably fine to just #undef the
two here (don't undef SC_COMP, __SC_3264 and SC_COMP_3264).

Changing the asm-generic header to not require the #undef would be nice,
but then we should do that for all 12 users of that file.
