Indeed. static-glapi does not get too much testing, plus it seems that
it's broken (in a way) for a loooong time.
It seems that we'll have to (temporary) resolve with shoving
dlopen(libglapi.so) into gbm, so that in time programs can nuke it from
their codebase. glapi is internal (implementation) detail that they
should not need to bother/know.
