Buildroot forces procps-ng to install binaries in the /bin insted of /usr/bin.
As a side effect libprocps.pc was installed at /lib/pkgconfig instead of
/usr/lib/pkgconfig. Which directory is not included into final image.

Added patch taken from buildroot's repo:
0e07a5ede package/procps-ng: install libprocps.pc in staging/usr/lib/pkgconfig/

Fix the warning (for perl < 5.21.x) whihch becomes an error
(for perl >= 5.21.x):

defined(@array) is deprecated at kernel/timeconst.pl line 373.
  (Maybe you should just omit the defined()?)

This error pops up on newer systems. It is not related with the change of
the buildroot, but with the host version of perl.

Instead of keeping the list of archives in build/download-info which should be
downloaded for buildroot, we use "make source" to do the same job.
However, the task of building buildroot had to split into 3 tasks:
--init (unpack and configure buildroot)
--download (download the source of used buildroot packages)
--build (compile buildroot packages, etc.)

The reason for this change is to avoid updating the download-info file when
buildroot package is updated. Additionally ltrace is not downloaded as an
archive, but it is cloned git repo. After the clone it is packed into archive.
In the current state our framework cannot do the same.

Remove binaries/usr/lib/libbfd-2.21.1.so and /usr/bin/nm from the repo.
Instead use the compiled versions in buildroot.

Patch the installation rule to install only "nm", when
PACKAGE_BINUTILS_TARGET is not used(!).
libbfd-2.21.1.so is installed by default by the installation rule of
PACKAGE_BINUTILS.

Binary nm was added in the commit:
d2a486cc

 rootfs_override: add /usr/bin/nm and its libbfd

make 3.82 splits the work differently. When using buildroot with
the make > 3.81 buildroot uses BR2_JLEVEL= (preferably 0 for automatic number
of jobs setting).
For make =< 3.81 BR2_JLEVEL= is ignored and build is done using only one job.
Passing -j allows to build with many jobs, but many warning messages are
printed:
make[2]: warning: -jN forced in submake: disabling jobserver mode.

Use BR_JLEVEL=0, this allows buildroot to pick automatically number of jobs.

In case there are errors it will print process name instead of pid.

Change the names of interfaces from wr0..wr17 (wrX) to wri1..wri18 (wriX).
Such change was done to avoid confusion that ports on the front panel are
numbered from 1 to 18, while in software they were numbered from 0 to 17.
Inconsistency started to show up especially in messages produced by software
causing confusion.

Be aware that even after these changes some software internally uses indexing
or ports from 0 to 17.
