No optimization flags were used during the build of the system in question.
As Hazel Russman just told, gmp may generate problems. I had once a lot porting a system from a PC to a laptop. The problem is, that gmp will use features from the CPU that is present at build time unless you use config.fsf ( See Bruce Dubbs, Re: [blfs-support] Portability problems ? and others)  In my case, the ported system was apparently working OK on the laptop, but no configurations or compilations was possible, also of course not the necessary ones for changing gmp.
Consider reading the threath with many  valuable advices.

Actually, I think the proposed port is worth a try. Yes, th ekernel will probably need different drivers, but gmp *should* be portable from an older system to a newer one.
