解决方法：

do_install() {
    install -d ${D}${libdir}
    cp -a --no-preserve=ownership ${S}/libsample.so.3.5 ${D}${libdir}
    ln -sf libsample.so.3.5  ${D}${libdir}/libsample.so.3

#For dev packages only
    ln -sf libsample.so.3  ${D}${libdir}/libsample.so
}

FILES_${PN} = "${libdir}/*.so.*"

#For dev packages only
FILES_${PN}-dev = "${libdir}/*.so"

INSANE_SKIP_${PN} = "ldflags"

#For dev packages only
INSANE_SKIP_${PN}-dev = "ldflags"
