Without this, it tries to run ./libtool, not the sys-prefixed libtool, which
fails, resulting in dynamic modules being disabled, which in turn results in
compiling the immodules directly into the gtk+3 library.
I tried switching it to using $LIBTOOL rather than hardcoding the path, as
LT_INIT sets LIBTOOL, but it didn't work, I didn't have time to dig further,
and this gets the job done for now.
