perf: fix do_compile failure with /tmp mounted with noexec
On a builder which has /tmp mounted nexec, the ARM64 generation of the sycall table will fail: [snip] |perf-1.0/tools/perf/arch/arm64/entry/syscalls//mksyscalltbl: /tmp/create-table-6VGPSt: Permission denied [snip] To avoid the permission denied error, we must instruct the perf build to place temporary files in an appropriate directory (versus always using /tmp). To do this, we need both a kernel source change to perf, and a recipe change to pass the temp directory in by a TMPDIR variable. The linux-yocto has a reference kernel change: [perf arm64: Fix generate system call table failed with /tmp mounted with noexec], that has also been submitted upstream mailing list linux-perf-users@vger.kernel.org Signed-off-by: Hongxu Jia <hongxu.jia@windriver.com> Reviewed-by: Bruce Ashfield <bruce.ashfield@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
