Odd. I've done two builds

        $ bitbake gstreamer1.0-plugins-bad

before each build I do

        $ bitbake -c cleansstate gstreamer1.0-plugins-bad

for one of the builds I have the following line in conf/local.conf; for the 
other, I don't:

        PACKAGECONFIG_pn-gstreamer1.0-plugins-bad = "opengl"

I've saved the entire contents of the following in ~/tmp/gst/no-opengl and 
~/tmp/gst/opengl (as appropriate):

        tmp/work/corei7-64-<distro>-linux/gstreamer1.0-plugins-bad/1.8.2-r0/

I believe the libgstgl is what the gstreamer-vaapi build wants, and in my case
it only exists in the opengl build.

I don't think so. The only packageconfig I have is for my chromium build:

        # $PACKAGECONFIG_pn-chromium-x11
        PACKAGECONFIG_pn-chromium-x11="disable-api-keys-info-bar ignore-lost-context impl-side-painting kiosk-mode"
        # $PACKAGECONFIG [4 operations]
        PACKAGECONFIG=""
            # Handle PACKAGECONFIG
            # PACKAGECONFIG ??= "<default options>"
            # PACKAGECONFIG[foo] = "--enable-foo,--disable-foo,foo_depends,foo_runtime_depends"
            pkgconfigflags = d.getVarFlags("PACKAGECONFIG") or {}
                pkgconfig = (d.getVar('PACKAGECONFIG', True) or "").split()
                        bb.error("%s: PACKAGECONFIG[%s] Only enable,disable,depend,rdepend can be specified!"
                appendVar('PACKAGECONFIG_CONFARGS', extraconf)
                # to get PACKAGECONFIG options are fixed to use PACKAGECONFIG_CONFARGS
                                error_msg = "%s rdepends on %s, but it isn't a build dependency, missing %s in DEPENDS or PACKAGECONFIG?" % (pkg, rdepend, rdep_data['PN'])
            # Check invalid PACKAGECONFIG
            pkgconfig = (d.getVar("PACKAGECONFIG", True) or "").split()
                pkgconfigflags = d.getVarFlags("PACKAGECONFIG") or {}
                        error_msg = "%s: invalid PACKAGECONFIG: %s" % (pn, pconfig)
