Jeffery To 782eda9750 zlib: Use relative paths in pkg-config metadata file
The buildroot pkg-config (in staging_dir/host/bin) overrides the prefix
and exec_prefix variables in *.pc files, to supply the correct
(buildroot) paths for callers. If other variables are not defined
relative to prefix and exec_prefix, then the returned values will be

The default zlib.pc file generated by cmake contains absolute paths.
This patches the file to use relative paths (relative to ${prefix} and

Hauke Mehrtens 8dcd941d8b tools/zlib: move zlib build to tools
This allows us to link the other tools against our libz and we do not
need the system zlib any more.

Only the static linked library is copied to the staging directory so we
have a statically linked library on all systems and not only on Linux.
This also adds the new dependencies of the packages which are depending
on zlib.

Jo-Philipp Wich 3f5e39e960 zlib: only enable NEON optimizations on eligible targets
Instead of inferring the availability of NEON support from the target
optimization flags, use a preprocessor test to decide whether to enable
ARMv8 NEON optimizations.

Fixes the following build error spotted by the mediatek/32 buildbot:

Daniel Engberg cbe71649bc package/libs/zlib: Add host build
Some packages such as Python/Python3 (host pip/pip3) needs this
to compile.

More detailed explanation provided by Alexandru:

"i need the zlib/host for Python/Python3 ; because, it seems the
host pip/pip3 needs this to work ; i suspect in older versions
this worked, because some of the host's build env would be used
in the build, and then the zlib-dev from the host distro would
be used ; now, the host-build does not seem to have any
-I/usr/include stuff, which is good

and it also seems that Python/Python3 does not like it if the
zlib-dev package is too old, so using this zlib/host would be
good for this as well"

but isn't in the CMake makefile for some reason.

Daniel Engberg 3acecba520 package/libs/zlib: Add ARM and NEON optimizations
This adds two optimizations for ARM:
NEON optimized Adler(-)32 checksum algorithm (ARMv7 and newer NEON CPUs)
ARM(v7+) specific optimization for inflate
I've also connected inflate optimization to the build using the following
source as template.

Hamish Guthrie 81a3d9ba31 licensing: Add licensing metadata to many packages Two new variables are introduces to many packages, namely PKG_LICENSE and PKG_LICENSE_FILES - there may be more than one license applied to packages, and these are listed in the PKG_LICENSE variable and separated by spaces. All relevant license files are also added to the PKG_LICENSE_FILES variable, also space separated.
The licensing metadata is put into the bin/<platform>/packages/Packages file
for later parsing. A script for that is on it's way!
