Fix compiling on Debian 10 and remove GLES1 support on Linux.

It seems Debian10 dropped support for GLES1. So with my only test-platform gone, I'll disable it by default for all Linux platforms. It's still enabled in Android (for now). Thought in the long run no one should  use GLES1 anymore anyway.
