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:

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"

The patch adds a new package zlib-dev. It contains all files needed for
compiling a program using the zlib library:
/usr/include/zconf.h
/usr/include/zlib.h
/usr/lib/libz.a
/usr/lib/pkgconfig/zlib.pc
