Description
A couple of patches to enable the building of (support for) EGL in port:mesa and port:libepoxy .
Not actually tested yet, but libEGL builds with only a source-level patch to replace some clock_gettime() functionality with (close) equivalents. Which may not even be required on 10.12 and up .

I've attached an update for Mesa 17.1.6 which also adds +llvmXY variants allowing to build the gallium swrast driver.
The main interest here is probably that this allows certain X11 applications to render to remote displays despite the Xquartz lack of GLX support. For instance, after building Qt5 for xcb, applications that require shared OpenGL contexts or similar less common features will fail on startup with a "failed to initialise GLX" error. When using EGL instead they will run normally.
