master as of this afternoon, 810b95e,

The full configuration I'm using, basically trying to build bare-bones
GLX and OSMesa libraries that only contain software OpenGL renderers:

meson --buildtype=release -Dprefix=/path/to/install/master
-Dglvnd=false -Dgallium-nine=false -Dgallium-omx=disabled
-Dgallium-opencl=disabled -Dgallium-va=false -Dgallium-vdpau=false
-Dgallium-xa=false -Dgallium-xvmc=false -Dvulkan-drivers=
-Dosmesa=gallium -Dglx=gallium-xlib -Degl=false -Dgbm=false
-Dopengl=true -Dgles1=false -Dgles2=false -Dshared-glapi=true
-Dllvm=true -Dswr-arches=avx2 -Dplatforms=x11,surfaceless
-Dgallium-drivers=swrast,swr -Ddri-drivers= /path/to/source/master

If I do a release build to silence the assert then I get a segfault.
Note that release or debug, swr works with glx via libGL.so and
segfaults when using libOSMesa.so
