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.
