[Mesa-dev] [PATCH] egl: Add MKDIR_GEN definition

[Daniel Stone]

Adding linux-dmabuf Wayland protocol files as generated did the right
thing, by prepending $(MKDIR_GEN) so autotools didn't try to write into
a build directory which didn't yet exist.

Unfortunately MKDIR_GEN needs to be defined in every Makefile it's used
in, and src/egl/ didn't actually have it. As unset variables expand to
NULL, it was silently being skipped.

Copy & paste the defintion to make sure drivers/dri2/ exists before we
try to generate files into it.
