So the prefix parameter should have no effect at all in your case,
no matter to what you set it.

It does:

rpmbuild -bb --define="_prefix /tmp/junk" SPECS/perf.spec

+ make -s -C tools/perf V=1 WERROR=0 NO_LIBUNWIND=1 HAVE_CPLUS_DEMANGLE=1 NO_GTK2=1 NO_STRLCPY=1 NO_BIONIC=1 prefix=/tmp/junk DESTDIR=/root/rpmbuild/BUILDROOT/perf-4.1.rc6-1.x86_64 all


Note that prefix=/tmp/junk when tools/perf/Makefile gets invoked.

[root@f21-vbox rpmbuild]# rpm -qvlp /root/rpmbuild/RPMS/x86_64/perf-4.1.rc6-1.x86_64.rpm | grep bin/perf
-rwxr-xr-x 2 root root 2382176 Jun 18 13:10 /tmp/junk/bin/perf
