Subject: [PATCH] Use environment variables for CC and PREFIX

Pull request #3 can break the compilation process. In my case, cc
points to gcc which cannot handle the `-G_DISABLE_DEPRECATED` and the
`-GDK_PIXBUF_DISABLE_DEPRECATED` command-line options whereas clang
works like a charm.

This commit allows the user to use whichever compiler they want
through environment variables such as:
    CC=clang make all

It also allows the user to define their preferred prefix with
environment variables:
    PREFIX=$HOME/.local/bin make install
