Thanks for the hint. I was using a relative path and starting in the
top of the kernel tree, so:

$ cd kernel
$ mkdir ../perf
$ make -s -C tools/perf JOBS=24 O=../perf

put everything in toos/perf (no suprise really)

I will change my script to use an absolute path (which I checked does
work fine). Sorry for the noise.
