Make running on kms possible on rpi #119

To run retroarch with kms on a raspberry, you need to explicitly disable videocore to prevent the configure script to autodetect it.

I'm getting 2 issues with my emulationstation ebuild :

the patch doesn't work
the cmake params don't work

Any idea why it's happening ?

Those changes should allow :

to build latest version from stable branch (master branch is broken, stable branch is the host of version 2.7.5 which is the latest)
to prevent bcm_host autodetection if gles/opengl flags are defined (on raspberry, bcm_host prevent emulationstation to work on top of a kms enabled sdl2 installation if raspberrypi-userland is installed)

Ok, i had a file at /etc/portage/env/games-emulation/emulationstation with some settings, it is building properly after removing it

Also added :

a modified libsdl2-2.0.8-r1 with support for kms and videocore auto-detection prevention
official raspberrypi-userland ebuild fails because of file colision, my ebuild fix this issue and work properly with pkg-config
mame2003-plus is a new libretro core, it is basicaly a mame2003 with lots of fixes + support for some mame2010 games

also, with my modification to the retroarch ebuild and my fixed raspberrypi-userland ebuild, you probably don't need this anymore in the retroarch ebuild (pkg-config + configure should handle it properly) : `

if use videocore; then
    export HAVE_VIDEOCORE="yes"
else
    export HAVE_VIDEOCORE="no"
    sed -i qb/config.libs.sh \
        -e 's:\[ -d /opt/vc/lib \] && add_library_dirs /opt/vc/lib && add_library_dirs /opt/vc/lib/GL::' || die 'sed failed'
fi`
