Yes.  The actual command line is:

make -C tools/perf -f Makefile.perf -s -O -j60 O=/home/sfr/next/perf NO_BPF_SKEL=1

The source directory is /home/sfr/next/next.  This is a PowerPC 64 little endian
build (on a PowerPC 64 little endian host).

OK, I just tested on my x86_64 laptop:
(I started with a clone of Linus' current tree)

pine:~/next/next (master)$ rm -rf ../perf
pine:~/next/next (master)$ mkdir ../perf
pine:~/next/next (master)$ make -C tools/perf -f Makefile.perf -s -O -j10 O=/home/sfr/next/perf NO_BPF_SKEL=1
