libtool family: upgrade from 2.2.6 to 2.2.10

This upgrades these recipes:
 libtool_2.2.6.bb -> libtool_2.2.10.bb
 libtool-native_2.2.6.bb -> libtool-native_2.2.10.bb
 libtool-cross_2.2.6.bb -> libtool-cross_2.2.10.bb
 libtool-nativesdk_2.2.6.bb -> libtool-nativesdk_2.2.10.bb
    Also fixes build failure caused by having aclocal.m4 built with older version
    of libtool.

Rebased these patches for the newer version sources
 add_dolt.patch
 cross_compile.patch
 dolt.m4

Changed this patch to fix documentation building for non-x86 archs
 prefix.patch

Rebased and changed to fix the building of ncurses recipe:
 trailingslash.patch

Also updated metadata variables like LICENSE & LIC_CHKSUM_FILES
