I think the combination of

CHOST="i486-pc-linux-gnu"

and

CXXFLAGS="-O3 -march=pentium4 -fprefetch-loop-arrays -funroll-loops -pipe" 

is wrong. You should set CHOST to "i686-pc-linux-gnu". But it might be that you have to recompile your whole system against this, because this settings are VERY sensitive!
