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
CPUTYPE?=pentium2
Note that by default the system is build with -O2 -fno-strict-aliasing -pipe.
