   	struct evsel evsel = {

  -			.read_format = read_format,

  +				.read_format = read_format,
  +			},

  gcc (GCC) 4.4.7

Also we don't need to include perf_event.h in
tools/perf/lib/include/perf/evsel.h, forward declaring 'struct
perf_event_attr' is enough. And this even fixes the build in some
systems where things are used somewhere down the include path from
perf_event.h without defining __always_inline.

We tried the total separation of the perf_thread_map struct in libperf,
but it lead to complications and much bigger changes in perf code, so we
decided to share the declaration.

Committer testing:

One has to build just libbperf to get this, building perf so far doesn't
trigger this, i.e. I tried:

  $ make O=/tmp/build/perf -C tools/perf

And the files above were not created, so one has to do:

  $ make O=/tmp/build/perf -C tools/perf/lib/
  make: Entering directory '/home/acme/git/perf/tools/perf/lib'
    LINK     /tmp/build/perf/libperf.so.0.0.1
