Subject: Remove some unnecessary dependencies
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2592acb8ff33674965e6acbfd29455ce83b5a111;p=sdk%2Femulator%2Fqemu.git

Remove some unnecessary dependencies

We remove all DMABUF support. We do not use it, and we cannot use it at
all, since we want to support non-Linux platforms. We also remove GBM,
as it is used only together with DMABUFs. Additionally we remove X11,
since we have no need to access it directly even on Linux.

While it would be preferable to embrace the conditional support, I could
not get this to work (building DMABUF-code resulted in immediate linker
errors for me, for example), and I felt like this is the cleanest way of
not building the code we aren't using.
