[Solved] Problem: Celeron Dual Core identified as Core i7

Question

Hello, I'm new in this forum and in Arch linux, so excuse me if I'm not clear. I want to rebuilt all my system and have it optimized for my computer. I have an Intel Celeron Dual Core.
cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 37
model name : Intel(R) Celeron(R) CPU P4500 @ 1.87GHz
As you can see in the model line it identifies my dual core as core i7. I checked this page http://en.gentoo-wiki.com/wiki/Safe_Cflags/Intel and it say that Intel Celeron Dual Core is model 15 and/or 23, but my system identifies it as 37.
I tryed these commands and they also identifies my cpu as corei7:
cc -march=native -E -v - </dev/null 2>&1 | grep cc1
gcc -Q --help=target -march=native
I am afraid that I'll have problems if I rebuild all my system with CXXFLAGS="-march=native -O2 -pipe". What do you advise me to do?

I believe that he intends to recompile everything (not just his kernel).
@OP:
Recompiling your kernel is only worth it if you modify the .config. Rebuilding everything else is pretty much useless (unless you want to add buffer overflow protection etc.).
