No, it just slipped through the cracks.

That regex looked a bit obscure, and there's a Python function we provide
that uses the Python standard library to do the same thing, so I ended up
with this locally:

# Move zlib shared libraries for target builds to $base_libdir so the
library
# can be used in early boot before $prefix is mounted.
do_install_append_class-target() {
if [ ${base_libdir} != ${libdir} ]
then
mkdir -p ${D}/${base_libdir}
mv ${D}/${libdir}/libz.so.* ${D}/${base_libdir}
libname=`readlink ${D}/${libdir}/libz.so`
ln -sf ${@oe.path.relative("${libdir}", "${base_libdir}")}/$libname
${D}${libdir}/libz.so
fi
}

Do you have any objections to this form instead?  I'm also thinking we
should rationalise the duplicated logic into a single implementation in
meta/classes/utils.bbclass...
