Since commit 4872a023a5 ("ui/gtk-egl: guest fb texture needs
to be regenerated when reinitializing egl") we get on Ubuntu
18.04.4 LTS and Debian Buster (oldstable):
$ ../configure --enable-virglrenderer
[...]
ui/gtk-egl.c: In function 'gd_egl_refresh':
ui/gtk-egl.c:159:13: error: implicit declaration of function 'egl_dmabuf_release_texture' [-Werror=implicit-function-declaration]
159 | egl_dmabuf_release_texture(vc->gfx.guest_fb.dmabuf);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~
ui/gtk-egl.c:159:13: error: this function declaration is not a prototype [-Werror,-Wstrict-prototypes]
ui/gtk-egl.c:159:13: error: nested extern declaration of 'egl_dmabuf_release_texture' [-Werror=nested-externs]
Fix by restricting the egl_dmabuf_release_texture() call to the
availability of the generic buffer management library (libgbm).
