ifndef _RUMPKERNEL in arm/cpufunc.h

[Alexander Nasonov <alnsn%yandex.ru@localhost>]

When aarch64 support was initially added, some structs/macros were
excluded from rump build. It's not clear to me what was the problem
because I can build evbarm64-el without that ifndef.

I need code under the guard to fix MKSLJIT build. OK to remove it?
