Add working build script for GLEW

I left GLEW in WIP until one of us tests it. However, it compiles fine
so I'll submit it for now.

recipes/wip/libs/other/glew/recipe.toml

-#TODO missing script for "make", see https://github.com/nigels-com/glew#linux-and-mac
-#TODO add the GLEW_OSMESA flag to enable the Mesa off-screen rendering
+# TODO Needs testing, but it compiles now
+
