also you can add command line argument to build.sh like that:

-V CPUFLAGS=-march=pentium3 -V COPTS="-O3 -funroll-loops -mfpmath=sse -msse -fno-strict-aliasing" \

and a line to kernel config like that:

makeoptions     COPTS="-O3 -march=pentium3 -funroll-loops -fomit-frame-pointer -fno-strict-aliasing"
