Week 32

 * Attempting to build enc_dec_demo for sunxi in cedarx-libs
 * Add includes to fix some build errors.
 * preprocessor failures at https://gist.github.com/anonymous/6194508 . File does not exist in repo.
 * Talk to #linux-sunxi suggested by wingrime to replace encoder_type.h with type.h.
 * Deal with awful makefile which uses CFLAGS improperly so set all -I includes in buildroot.
 * Finally beat the preprocessor only to find a bunch of errors at the compile stage. https://gist.github.com/anonymous/6194791
 * Suggested by wingrime to move to A20 SDK but he did not elaborate further. The errors appear to be an out of date version of types.h.
 * Notice libcedarv/ /sample: attempt to build sample. Success!
 * New issue on udev created by rebase. https://gist.github.com/anonymous/6195121 (possibly due to linaro toolchain)
 * Small udev bug fix patch for udev http://lists.busybox.net/pipermail/buildroot/2013-August/076370.html. Accepted.
 * Need to find *.pmp for input to sample application.
 * Adding glmark2
 * Created package dir and added basic info.
 * requires jpeglib.h. fixed.
 * requires libpng12. Fixed.
 * requires libdrm and libdrm requires xlibs. build fails due to same error as https://gist.github.com/anonymous/6195121 therefore switch to soft-float CS toolchain.
 * requires mesa3d. Fixed
 * Bug in mesa3d build see https://gist.github.com/anonymous/6197590.
 * host-libxml2 does build the python bindings and something is installed (not sure if everything.) Attempting to determine if this is an unclean build issue. It may have been.
 * Another bug https://gist.github.com/anonymous/6197871 . It appears -m32 is passed in some absurd way. Added patch from http://lists.freedesktop.org/archives/mesa-dev/2012-April/021046.html
 * Bug GLchar https://gist.github.com/anonymous/6198693. it's a simple typedef char GLchar; fix.
 * Bug need libgbm from mesa only in 7.11.x and up. Bump mesa3d to 7.11.2.
