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
