Try this:

do_install() {
    install -d ${D}${libdir}
    # Install all libraries into the image folder
    for file in ${WORKDIR}/location/lib*; do
        install -m 0644 $file ${D}${libdir}
    # Change directory to the image folder
    cd ${D}${libdir}
    for libfile in lib*; do
        # Strip the version
        stripped_libversion=$(echo $libfile | sed 's/\.so.*/.so/')
        ln -sf $libfile $stripped_libversion
