perf build: Align the names of the build tests:

  $ make -C tools/perf build-test
  make[1]: Entering directory `/home/acme/git/linux/tools/perf'
                 make_pure_O: cd . && make -f Makefile  O=/tmp/tmp.mPx0Cmik3f DESTDIR=/tmp/tmp.U0SUmVbtJm
            make_clean_all_O: cd . && make -f Makefile  O=/tmp/tmp.Yl5UzhTU7T DESTDIR=/tmp/tmp.fop1E4jdER clean all
                make_debug_O: cd . && make -f Makefile  O=/tmp/tmp.pMn2ozBoXC DESTDIR=/tmp/tmp.azxhDp5sEp DEBUG=1
           make_no_libperl_O: cd . && make -f Makefile  O=/tmp/tmp.qJPiINMtA7 DESTDIR=/tmp/tmp.KNMrLeGDxZ NO_LIBPERL=1
  <SNIP>

More needs to be done to make it more compact, i.e. elide the '-f Makefile',
remove that 'cd . &&', move the DESTDIR= and O= to the end, as they don't
convey that much information besides the fact that they are being set to some
random directory just for this build, move the meat, i.e. the meaningful
feature disabling bits to the start, etc.
