bpftool will enabled libbfd and libopcodes which gets picked up by perf
as libraries to link against. Add those missing dependencies when either
of these packages are enabled.

libzstd from the packages feed gets picked up. Remove it.
Fixes:
Package perf is missing dependencies for the following libraries:
libzstd.so.1

For this package CFLAGS have to be passed via EXTRA_CFLAGS.
On arm this bug causes build to fail because no -fPIC is present in CFLAGS.

This package fails with a strange error when building with musl when NLS
is enabled. The configuration thinks that libelf is not present, even
though DEPENDS contains +libelf, because when NLS is enabled, libelf.so
depends on libintl, and the correct LDFLAGS are missing for
libintl-full. This then causes the configuration script to check for
glibc, but this fails because we are using musl.

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.

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.

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.

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.

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.

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).

This fix contains 2 parts:
- kernel 4.1: backport upstream patch "perf build: Do not fail on missing Build file"
- add NO_LZMA=1 to perf MAKE_FLAGS to disable LZMA support

There are some places where there is a redundant declaration of
strlcpy() that prevents building perf otherwise.

perf was in the oldpackages repository, but it makes more sense to have
it part of the default package set since we build it from the Linux
kernel sources.
