CPUTYPE Now Required?

[Jason C. Wells]

While trying to build RELENG_6 I receive this error:

make: fatal errors encountered -- cannot continue
"/usr/src/Makefile.inc1", line 142: warning: "MAKEFLAGS= CPUTYPE=pentium 
/usr/obj/usr/src/make.i386/make  -f /dev/null -m /usr/src/share/mk -V 
CPUTYPE" returned non-zero status
"/usr/src/Makefile.inc1", line 144: CPUTYPE global should be set with ?=.

I've never set CPUTYPE in the past.  I don't want specific CPU 
optimizations as I am building for multiple generations of processor.

What is a person to do?

Later,
Jason
