Use beforeinstall instead of adding another target.
'make clean' should be easy to do, just add what you built to CLEANFILES...
you may wish to move the building part of sanitycheckprog to build, not
beforeinstall...
oh, and use .OBJDIR, then it doesn't matter if you forgot to run obj.
e.g.,
test a fragment like that:
OBJ2= sanitycheckprog.o
P2= sanitycheckprog
# XXX native build only
.if !defined(HOSTCC)
all: ${P2}
${P2}: ${OBJ2}
$(CC) -o $@ ${OBJ2} -Wl,--dynamic-linker,${.OBJDIR}/$(PROG)
beforeinstall:
./${P2}
.endif
CLEANFILES += ${P2} ${OBJ2}
