Created attachment 362038 [details, diff] Patch using AUTOTOOLS_PRUNE_LIBTOOL_FILES=all This is the last package that uses the deprecated function. Instead, please use AUTOTOOLS_PRUNE_LIBTOOL_FILES=all variable that would avoid additional call. This applies to 1.9* as well. Patch attached but I can't test it due to deps.
I commited your patch, thanks.
