tools/perf/build: Pass through all targets to Makefile.perf
Jiri reported that 'make .o' stopped working:
> [jolsa@krava perf]$ make -f Makefile perf.o
> cc -c -o perf.o perf.c
> In file included from builtin.h:4:0,
> from perf.c:9:
> util/util.h:74:24: fatal error: lk/debugfs.h: No such file or directory
> compilation terminated.
> make: *** [perf.o] Error 1
This is due to GNU make having built-in rules for popular targets such
as *.o. Clear them out so that all targets as passed through to Makefile.perf.
