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:
