'pkg-config --libs glew' returns unnecessary flags: -lX11 -lGLU -lGL #301

$ pkg-config --libs glew
-L/usr/local/lib -lGLEW -lX11 -lGLU -lGL

It should only return -L/usr/local/lib -lGLEW. More flags are returned when the --static argument is given.

Redundant link flags cause ports depending on GLEW also add redundant dependencies, because this is based on what libraries binaries are link with.

Unless I am mistaken, for the actual link steps when building glew it's just visualinfo that requires -lGL at all (so there is also some needless linking going on for libGLEW and glewinfo that would be appropriate to remove)
