perf annotate: Show raw form for jump instruction with indirect target (2016-12-05 17:21:57 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

Fixes:

- Do not show a bogus target address in 'perf annotate' for targetless powerpc
jump instructions such as 'bctr' (Ravi Bangoria)

- tools/build fixes related to race conditions with the fixdep utility (Jiri Olsa)

- Fix building objtool with clang (Peter Foley)

Infrastructure:

- Support linking perf with clang and LLVM libraries, initially statically, but
this limitation will be lifted and shared libraries, when available, will
be preferred to the static build, that should, as with other features, be
enabled explicitly (Wang Nan)

Signed-off-by: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

----------------------------------------------------------------
Jiri Olsa (7):
tools build: Make fixdep parsing wait for last target
tools build: Make the .cmd file more readable
tools build: Move tabs to spaces where suitable
perf tools: Move install-gtk target into rules area
perf tools: Move python/perf.so target into rules area
perf tools: Cleanup build directory before each test
perf tools: Add non config targets

Peter Foley (1):
