Re: Compilation failure with WITH_DTRACE_TESTS on mips/mips and powerpc/powerpc; it's trying to compile a host object on mips/powerpc because MAKEOBJDIRPREFIX is incorrect

It would help if you could indicate what you think the right value
should be.

If you are doing this on current (ie MAKE_VERSION==20151020), adding -w
would be useful, since will report entering src and obj dirs.

what dir do you execute that in?
I'm *guessing* cddl/usr.sbin/dtrace/tests/common/json.

It's actually quite useful when reporting/describing problems to do
everything from src eg.

make -w -C cddl/usr.sbin/dtrace/tests/common/json

leaves very little room for confusion.

What else do you expect in .PATH?
I didn't see anything in the Makefile or ../../Makefile.inc1 to add
anything else

You may also find it useful to set MAKE_PRINT_VAR_ON_ERROR
to a list of variables - that will be reported when make dies.
eg.

MAKE_PRINT_VAR_ON_ERROR=".CURDIR .OBJDIR MACHINE MACHINE_ARCH .PATH"
