Updating config for building on aarch64

[clort81]

Looks like config.guess and config.sub are out of date
g/gitweb/?p=config.git;a=blob_plain;f=config.guess;hb=HEAD' -O config.guess
wget 'http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD' -O config.sub

Additionally uname -X is unsupported now.

Also gtk/gtk.h isn't found.

It seems this is needed when configure generates Makefile:
pkg-config --cflags --libs gtk+-2.0

exporting as CFLAGS the output of pkg-config gets me past the include errors, but then a bunch of gdkcolor.h errors

The whole build system needs a massive update

Check out my fork if you want something that compiles on modern distros, I also compiled it on a distros released in 2009, so it's generic enough, only gtk2 is supported

I've submitted mhwaveedit to flathub, aarch64 and x86_64 both should work now.
