fixpatch: projectm 3.1.12

This PR should fix `dpf-plugins` building fault: https://archriscv.felixc.at/.status/log.htm?url=logs/dpf-plugins/dpf-plugins-1.7-2.log , although `projectm` itself can be built successfully with current riscv64 patch.

The current PR use `autoreconf` to update the outdated `config.{guess,sub}` , while also updating `libtool` at the same time, which breaking the behavior of  `sed -i -e 's/ -shared / -Wl,-O1,--as-needed\0/g' libtool` in the original PKGBUILD, which causes projectm to be overlinked, more specifically linking `libprojectm.so` to `libqt5gui.so` and `libqt5opengl.so`, meanwhile `projectm`'s depends not containing `qt5-base`.

Although, the `dpf-plugins` doesn't depend on `qt5-base` but `projectm`, then, boom.
