Julien Olivain f10488a411 package/iperf3: fix build with libatomic 
Commit 9f94b3b354 "package/iperf3: bump to version 3.16" updated
the package but forgot to reflect a breaking change mentioned in
the release note [1], "iperf3 now requires pthreads and C atomic
variables to compile and run".

When the toolchain has no atomic support, or the libatomic is not
added in the linker flags, the compilation now fail with output:

    arm-buildroot-linux-gnueabi/bin/ld: ./.libs/libiperf.so: undefined reference to '__atomic_load_8'

This issue can be seen when running the iperf3 runtime test, with
command:

    support/testing/run-tests \
        -d dl -o output_test \
        tests.package.test_iperf3

This commit fixes the issue by adding a dependency on
BR2_TOOLCHAIN_HAS_ATOMIC and by adding an upstream patch to detect
if linking to libatomic is needed.

Fixes: [2]

README 

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on OFTC IRC.
