Can you make it so that make O=/path/to/build works?
I tried running this on my test box, which has /home/rostedt mounted read only from my build box, and I get this:
[root@bxtest ftrace]# make O=/tmp for TARGET in ipmodify; do \ make -C $TARGET; \ done; make[1]: Entering directory `/work/git/linux-trace.git/tools/testing/selftests/ftrace/ipmodify' make -C /lib/modules/3.18.0-rc1-test+/build M=/work/git/linux-trace.git/tools/testing/selftests/ftrace/ipmodify ipmodify.ko make[2]: Entering directory `/home/rostedt/work/git/nobackup/bxtest/trace' CC [M] /work/git/linux-trace.git/tools/testing/selftests/ftrace/ipmodify/ipmodify.o /bin/sh: ./scripts/recordmcount: Permission denied make[5]: *** [/work/git/linux-trace.git/tools/testing/selftests/ftrace/ipmodify/ipmodify.o] Error 1 make[4]: *** [ipmodify.ko] Error 2 make[3]: *** [sub-make] Error 2 make[2]: *** [__sub-make] Error 2 make[2]: Leaving directory `/home/rostedt/work/git/nobackup/bxtest/trace' make[1]: *** [ipmodify.ko] Error 2 make[1]: Leaving directory `/work/git/linux-trace.git/tools/testing/selftests/ftrace/ipmodify' make: *** [all] Error 2
