While building kernel you need to have separate flags
for internal objects and for host programs.
First, I thought I need to separate it as you say, but
perf build is separated from kernel built process, so
AFAICS we can use obj-y with no harm in perf.
It's quite possible I missed something and kbuild folks
prove me wrong ;-)
The Makefile.kbuild defines flags to be used for obj-y.
