The Linux kernel makefile by default does one thing at a time so you are
testing 1 Celeron not 2.

Compiling a large source tree like the Linux kernel includes a lot of disk
I/O. Differences in the disk subsystem can easily weight more than
differences in CPU's. 
You can verify this by putting and EIDE dma mode 2 and a brand new 10E3
rpm UW SCSI disk in the same machine and see what difference it makes.
