Revert "generic, x86: fix __per_cpu_load relocation"

This reverts commit 5a611268b69f05262936dd177205acbce4471358.

It is causing occasional boot crashes, caused by certain
linker versions (GNU ld version 2.18.50.0.6-2 20080403) messing up:

 82dcc000 D __per_cpu_load
 c16e6000 A __per_cpu_load_abs

The __per_cpu_load value is out of whack. Hpa noticed the following
detail:

  * (gdb) p/x -(0xc16e6000-0x82dcc000)
  * $2 = 0xc16e6000
  * I.e. one is the other << 1

The two symbols should be equal.
