175729fc2c perf tools: Remove needless includes from cache.h
The cache.h header doesn't use any of the definitions in some of the
headers it includes, ditch them and fix the fallout, where files were
getting stuff they needed just because they were including it, sometimes
not using what it really exports at all.

78f69b5865 perf tools: Add more toolchain triplets
Add few more triplets based on Fedora and Ubuntu binutils (cross tools).

Before applying patch on x86:

  ( Install binutils-powerpc64-linux-gnu.x86_64 )
  $ perf report -i perf.data.powerpc --vmlinux vmlinux.powerpc \
      --objdump powerpc64-linux-gnu-objdump

After applying patch on x86:

  $ perf report -i perf.data.powerpc --vmlinux vmlinux.powerpc

I.e. it will find the right objdump from the environment data recorded
in the perf.data file + these triplets.

eebd0bfca5 perf env: Rename some leftovers from rename to perf_env
In ce80d3bef9 ("perf tools: Rename perf_session_env to perf_env") we
forgot to rename a few functions to the "perf_env" prefix, do it now.

ce80d3bef9 perf tools: Rename perf_session_env to perf_env
As it is not necessarily tied to a perf.data file and needs using in
places where a perf_session is not required.

046625231a perf tools: Introduce zfree
For the frequent idiom of:

   free(ptr);
   ptr = NULL;

Make it expect a pointer to the pointer being freed, so that it becomes
clear at first sight that the variable being freed is being modified.

ff6f7778a6 perf tools: Don't try to lookup objdump for live mode
Arnaldo reported that annotation during perf top resulted in a segfault.
It was because the env->arch was NULL and we don't set it for a live
session.  In fact, no need to look up objdump in this case since we can
use system's default (native) objdump.

48ed0ece1b perf tools: Use normalized arch name for searching objdump path
David reported that perf report for i686 target data on x86_64 host
failed to work because it tried to find out cross-compiled objdump.

However objdump for x86_64 is compatible to i686 so that it doesn't need
to do it at all.  To prevent similar artifacts, normalize arch name when
comparing host and file architectures.

to find cross-built objdump path.

architectures).
