You can't do this with PACKAGECONFIG alone, you'd need to use Python, i.e. 
something like this:

PACKAGECONFIG ?= "gl gles2"
PACKAGECONFIG[gl] = "..."
PACKAGECONFIG[gles2] = "..."
...

python __anonymous() {
    packageconfig = (d.getVar("PACKAGECONFIG", True) or "").split()
    flavors = []
    if "gles2" in packageconfig:
        flavors.append("x11-gles2")
    if "gl" in packageconfig:
        flavors.append("x11-gl")
    if flavors:
        d.appendVar("EXTRA_OECONF", " --with-flavors=%s" % ",".join(flavors))
}

Cheers,
Paul
