Description of problem:
-----------------------
I can't compile kernel-source-2.4.21-1.1931.2.411.ent when the following is set
in the .config file:

CONFIG_X86_UP_APIC=y
CONFIG_X86_UP_IOAPIC=y
CONFIG_X86_LOCAL_APIC=y
CONFIG_X86_IO_APIC=y

During compile, I get the following errors when performing a "make rpm":

Version-Release number of selected component (if applicable):
kernel-source-2.4.21-1.1931.2.411.ent

How reproducible:
Always

Steps to Reproduce:
1. Install kernel-source-2.4.21-1.1931.2.411.ent
2. Enable APIC and IOAPIC support for UP
3. Try compiling
    
Actual results:
The kernel won't compile

Expected results:
The kernel should compile

Additional info:
I have attached the ".config" file used to build the kernel.
