It only modifies _CPUCFLAGS:

_CPUCFLAGS = -mcpu=pentiumpro

Which as you can see at the bottom of bsd.cpu.mk:

.if !defined(NO_CPU_CFLAGS)
CFLAGS += ${_CPUCFLAGS}
.endif

Thus it is quite responsive to NO_CPU_CFLAGS:

> make -V CFLAGS CPUTYPE=""
-O -pipe -mcpu=pentiumpro

> make -V CFLAGS CPUTYPE="" NO_CPU_CFLAGS=1
-O -pipe
