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....
