Rosen Penev 475a504dbc perf: Add libunwind only if selected
The depends are totally wrong. libunwind does not work with powerpc and
i386 as it needs glibc.

Instead of duplicating the platforms, just change the dependency.

Petr Štetiar 16ac5c4fbd perf: simplify the build process
Redirect the build output to PKG_BUILD_DIR instead of copying over
complete source code.

Build tested on following targets:

 x86/64 ar7/generic ipq40xx/generic imx6/generic ar71xx/generic
 ramips/mt7621 ramips/mt7620 sunxi/cortexa7

Run tested on imx6/apalis.

Hauke Mehrtens 1325e74e0c kernel: Remove support for kernel 3.18
No target is using kernel 3.18 anymore, remove all the generic
support for kernel 3.18.

The removed packages are depending on kernel 3.18 only and are not used on
any recent kernel.

perf: restrict libunwind dependency to archs that actually support libunwind
Allow building perf on uncommon targets again.

Depending on the kernel version, not all of these archs will actually use
libunwind in perf. Still, it seems simpler and less error-prone to use the
same list that is defined in the libunwind package.

Florian Fainelli f50079985c perf: Depend on KERNEL_PERF_EVENTS
The kernel needs to have PERF_EVENTS built otherwise we will run into
the following:

root@(none):/# perf top
perf_event_open(..., PERF_FLAG_FD_CLOEXEC) failed with unexpected error
89 (Function not implemented)
perf_event_open(..., 0) failed unexpectedly with error 89 (Function not
implemented)
Error:
The sys_perf_event_open() syscall returned with 89 (Function not
implemented) for event (cycles).
/bin/dmesg may provide additional information.
No CONFIG_PERF_EVENTS=y kernel support configured?

Make sure this functional dependency is captured.

Alexey Brodkin 5dc76a4258 perf: Disable perf for ARC770 only, enable for ARC HS38
Toolchain built for ARCv1 (read for ARC700 cores) by default has
disabled atomic ops (-mno-atomic). When we build Linux kernel for ARC770
which has LL/SC instructions and thus may handle normally atomic ops we
explicitly add "-matomic" in CFLAGS. But since user-space perf utility has
no way to extract CPU config options from Kconfig/defconfig it uses
compiler default settings.

In case of ARCv2 (read ARC HS38) atomics are enabled by default and so
perf builds perfectly fine thus reenabling perf for ARC HS38 (actually
for non-ARC700 targets).
