Alas, this has not correctly been reflected in the libcairo2 symbols
file which sets 1.12.4-5~ as the minimum version for
cairo_egl_device_create, rather than 1.12.14-5~.  Cloning a copy of this
bug to cairo.

Indeed, egl_gallium.so is linked against libllvmradeon9.1.3.so, but
there is no dependency information for that, as can be seen in the mesa
build logs:

,----
| dpkg-shlibdeps: warning: Can't extract name and version from library name `libllvmradeon9.1.3.so'
`----

Reassigning this part to mesa.
