CHANGES: extend 2016.11-rc1 changelog

Browse Source 
- Longer explanation of multi-BR2_EXTERNAL
- Mention nobody UID 99 -> 65534 change
- Mention removal of BR2_DEPRECATED
- Mention use of system cmake
- Mention new dependency on ExtUtils::MakeMaker. The other perl
  dependencies are not mentioned since they only apply if mpv is built.
- Mention the $(STAGING_DIR)/$(O) check.
- Mention unsafe path detection in -isystem etc.
- Mention linux-tools split.
- Mention changes in legal-info.
- Mention that pseudo is used instead of fakeroot.
- Correct the info of toolchainfile.cmake: it still sets cflags but it
  doesn't force them anymore (doesn't append).

Fixes all over the tree and new features.
It is now possible to specify multiple BR2_EXTERNAL
directories. The required files in a BR2_EXTERNAL directory
have changed to accomodate this feature. Refer to the
documentation for details of how to update them. External
trees now have a name and a description. Also, it is possible
to override a defconfig in the external tree.
The default skeleton now uses UID 65534 for the "nobody"
user instead of UID 99, like most distros do. See
https://lwn.net/Articles/695478/ for a complete discussion.
Programs and configuration files that explicitly refer to UID
99 will have to be updated.
When the build environment already has a suitable cmake version
(3.1 or later), that one will be used instead of building
host-cmake. This can speed up the build significantly.
The ExtUtils::MakeMaker perl module is now required in the
build environment.
An additional check is done during the build that files are
not installed in the output directory within the output
directory. This happens e.g. when the target directory is
contained both in --prefix and in DESTDIR. The build will
terminate with an error message that specifies which package
and which file caused the failure.
The concept of "deprecated packages" and the BR2_DEPRECATED
option have been removed. Instead, packages are removed
immediately. Packages are only removed when they don't work
for some reason. If you still need a removed package and
you have a solution for the problem(s) that caused the
removal, please contribute it.
Architecture: support for sh64 removed, improved support for
MIPS core selection,

Toolchain: support for musl powerpc64le, mips64 and mipsr6
toolchains, ARC toolchain components updates, gcc 6.x series
bumped to 6.2.0, default binutils version switched to 2.26,
default gcc version switched to gcc 5.x, Linaro toolchains
updated, uclibc-ng bumped to 1.0.19.
Core infrastructure: support for multiple BR2_EXTERNAL
directories.
updated, uclibc-ng bumped to 1.0.19. GCC is now always built
with TLS support. Checking of unsafe compiler options (that
point to host directories) has been extended with -isystem,
-idirafter and -iquote.
Package infrastructure: new variable $(PKG)_DL_OPTS, addition
of <pkg>-show-rdepends to list reverse dependencies, and
<pkg>-graph-rdepends to graph reverse dependencies.
<pkg>-graph-rdepends to graph reverse dependencies. Linux tools
are now in a separate linux-tools package instead of in the
kernel build. Fakeroot has been replaced by pseudo.
CMake support: the toolchainfile.cmake file now provides a
definition of the CMAKE_BUILD_TYPE variable. The
toolchainfile.cmake also no longer passes the compiler/linker
toolchainfile.cmake also no longer forces the compiler/linker
flags defined by Buildroot.
New defconfigs: WaRP7, Solidrun's MX6 Cubox/Hummingboard,

Removed packages: binutils 2.24, gcc 4.7, ipkg,

Documentation: the list of packages that was present in the
Buildroot manual has been removed.
Legal info: the "licenses.txt" file that concatenates all
license texts is no longer generated - it was not considered
useful. The manifest.csv contains an empty cell instead of
"not saved" when no license file is available.
Other: addition of a DEVELOPERS file listing developers taking
care of packages or architectures.
