Using sparcv9cap.c results to failure to buildworld. so I modified
CPUID_SRCS setting in crypto.inc like: 
----8<--------8<----
CPUID_SRCS += sparccpuid.S
.if ${MACHINE} == "sparc64"
CPUID_SRCS += sparcv9cap.c
.else
CPUID_SRCS += sparccap.c
.endif
CPPFLAGS += -DOPENSSL_CPUID_OBJ
----8<--------8<----

Finally, build setting on 9.1 was just restored for 32 bit
CPUs...
