Setting COPTFLAGS is discouraged, because you risk breaking the kernel. In 
particular, the kernel can not use any floating point operations including 
simd operations, which you explicitly enable above. May I suggest that you 
first try to rebuild the base system without any CFLAGS set but simply 


Note that by default the system is build with -O2 -fno-strict-aliasing -pipe.
