Subject: [PATCH v5 1/6] perf tools: configure tmp path at build time
From: Irina Tirdea <irina.tirdea@...el.com>
Temporary perf files are hardcoded to point to /tmp. Android does not have
a /tmp directory so it needs to set this path at compile time.
Add a compile-time definition (PERF_TMP_DIR) in the Makefile that sets the path
to temp directory. By default it points to /tmp.
