xdt-autogen: Fix aclocal macro search path
Probably a regression introduced in 2759f19c.
I don't know if this is the best way to do it, but it works (see also https://www.gnu.org/software/automake/manual/html_node/Macro-Search-Path.html). Tested building xfce4-notifyd with xfce4-dev-tools 4.18.0 installed in /usr
and xfce4-dev-tools 4.19.0 installed in /usr/local
. xfce4-notifyd requires XDT_CHECK_OPTIONAL_FEATURE
so the build fails without this patch.
Fixes: #62 (closed)
