[PATCH 4.0 121/220] perf tools: Fix perf-read-vdsox32 not building and lib64 install dir

[Greg Kroah-Hartman]

4.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "H.J. Lu" <hjl.tools@xxxxxxxxx>

commit 76aea7731e7050c066943a1d7456ec6510702601 upstream.

Commit:

  c6e5e9fbc3ea ("perf tools: Fix building error in x86_64 when dwarf unwind is on")

removed the definition of IS_X86_64 but not all places using it, with
the consequence that perf-read-vdsox32 would not be built anymore, and
the default lib install directory was 'lib' instead of 'lib64'.

Also needs to go to v3.19.
