    sys-libs/zlib: fix CC detection in configure
    
    Notably fixes multilib (although it actually silently skipped
    for me) in at least one way.

    sys-libs/zlib: revbump 1.2.12 for configure fix
    
    For me, it silently installed no 32-bit lib (or tried to build
    it statically, which then didn't get installed), so let's
    be cautious.
    
    Still unkeyworded until later though.
