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
incorrect.

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

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.
