No, mesa and mesa-gl intentionally conflict.  mesa-gl provides GL,
emgd-driver-bin provides EGL and GLES, your machines shouldn't need
both mesa and mesa-gl.

To be honest GL platforms that don't ship their own headers are
*totally broken* and using mesa's headers is basically the same as
crossing your fingers and praying to $DEITY. Platforms that do this
need to be fixed, not worked around, and taking Mesa's headers without
editing them is just wrong.
