Is there any software utility that will detect hardware automatically and give compile instructions which will automatically compile the system to its optimum level? I remember using a hardware detect utility
Not really. Most of the optimisations are taken care of by the compiler, and Gentoo ships with reasonable defaults. Most other distributions offer binaries, so you don't have to worry about such things. If you are trying to optimise, -O2 or -O3 will do more for your binary than the CPU specific flags, except for thigs like the kernel, glibc and openssl.
The parameters are not secret, they are just compiler options.
