>Description:

Building sparc bootblocks issues a warning about Makefile.buildboot:
CFLAGS=         ${${ACTIVE_CC} == "clang":? -Oz -fomit-frame-pointer : -Os } -f$

nbmake: Bad conditional expression ` == "clang"' in  == "clang"? -Oz -fomit-frame-pointer : -Os 


>How-To-Repeat:

cd sys/arch/sparc/stand/boot && $TOOLDIR/bin/nbmake-spard obj

>Fix:

Move include of bsd.own.mk before include of Makefile.buildboot ?
