[PATCH] make 2.4.32 work on i486 again

Booting the 2.4.32 kernel compiled for a i486 on an i486 box fails,
because "Kernel compiled for Pentium+, requires TSC feature!" (printed
from check_config() include/asm-i386/bugs.h). To reproduce, select 486 in
the kernel configuration and grep CONFIG_X86_TSC .config
