x86: Fix binutils-2.21 symbol related build failures

New binutils version 2.21.0.20110302-1 started checking that the symbol
parameter to the .size directive matches the entry name's
symbol parameter, unearthing two mismatches:

  AS      arch/x86/kernel/acpi/wakeup_rm.o
  arch/x86/kernel/acpi/wakeup_rm.S: Assembler messages:
  arch/x86/kernel/acpi/wakeup_rm.S:12: Error: .size expression with symbol `wakeup_code_start' does not evaluate to a constant

  arch/x86/kernel/entry_32.S: Assembler messages:
  arch/x86/kernel/entry_32.S:1421: Error: .size expression with
  symbol `apf_page_fault' does not evaluate to a constant

The problem was discovered while using Debian's binutils
(2.21.0.20110302-1) and experimenting with binutils from
upstream.

Thanks Alexander and H.J. for the vital help.
