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'
