Complementary patch to Herbie Hopkins' patch attached to gentoo bug #111073.
His patch fixes up issues where mysql ebuilds using mysql.eclass don't locate
zlib properly on multilib 64-bit systems. This patch applies the same fixage
to *all* other affected ebuilds (which aren't using the eclass), including
version 4.1.14 which is marked stable at the time of writing.
