'-j'.  I instaled the patch on my 10-STABLE system back on January 1, 2015.
Since I wanted readable output should I get n error, I did not use '-j'. It
worked just fine.

Today I updated my sources to r277334, deleted /usr/obj/*, made buildworld,
and then tried "make -DNO_CLEAN -j6 buildkernel". It failed to make depend
in sys/dev/drm2. The error message just has:
--- depend_subdir_drm2 ---
mkdep: compile failed
--- depend_subdir_dtrace ---
---
/usr/obj/usr/src/sys/GENERIC/modules/usr/src/sys/modules/dtrace/fasttrap/machine

--- depend_subdir_drm2 ---
*** [.depend] Error code 1

*** [_sub.depend] Error code 2

make[4]: stopped in /usr/src/sys/modules/drm2
1 error

If I than either clean out MODULES and "make -DNO_CLEAN buildkernel" or
just do the parallel build and, after the failure, do "make -DNO_CLEAN
buildkernlel", the build works fine.

I'm unsure how to get detail error information from the modern make used
today, so I have no added information. I'll be happy to try again if I know
how to get verbose build output from buildkernel.
