Subject[PATCH 01/10] perf tools: Compile perf with libperf-in.o instead of libperf.a
Date
There's no need for perf build to use libperf.a,
we can use directly libperf-in.o.

The libperf.a stays as a target if needed:

$ make libperf.a
...
CC util/pmu.o
CC util/pmu-flex.o
LD util/libperf-in.o
LD libperf-in.o
AR libperf.a
