Log Message:
Update cpuflags to 1.06:
On NetBSD use 'sysctl -n machdep.sse2' and 'sysctl -n machdep.sse'
to determine whether to add '-mfpmath=sse -msse2' or '-mfpmath=sse
-msse' to CPUFLAGS. This ensures these values are set correctly in
the event of the kernel not providing sufficient identification
details on the CPU.  - from Blair Sadewitz
