You recompiled binutils trough configure and make? Maybe the binutils are 
pentium optimized.
I had the same problem on my linux-from-scratch. It was built on an athlon, and 
configure detectet an i586, and optimized for it.

You might have a look in the Makefile of your binutils sources, if you didn't 
delete them. If you are totally unfamiliar with that, you can send it in 
personal to me, and I'll do my best.

Check the march options in the makefile, or try configure --target=i486 read 
the help for these options, --build=i486 --host=i486 and decide wether you need 
them.
