This class adds a postfunc to do_install to remove all .la files installed by
libtool, so that they are absent from both the sysroots and target packages.
If a recipe needs these files to be installed then it can be overridden by
setting REMOVE_LIBTOOL_LA.
Note that this class isn't enabled by default.
