perf tools: Fix parallel build including 'clean' target



Do not parallelize 'clean' with other targets, figure out if it is
present and do it first, then the other targets.

Noticed with:

  tools/perf> make -j24 clean all

   LD       arch/libperf-in.o
   LD       plugin_xen-in.o
 arch//libperf-in.o: file not recognized: File truncated
 make[3]: *** [arch/libperf-in.o] Error 1
 make[2]: *** [arch] Error 2
 make[2]: *** Waiting for unfinished jobs....
   AR       libapi.a
