xlib_libXxf86vm is an optional dependency for the DRI drivers,
quote from mesa3d/configure.ac:
# add xf86vidmode if available
PKG_CHECK_MODULES([XF86VIDMODE], [xxf86vm], HAVE_XF86VIDMODE=yes, HAVE_XF86VIDMODE=no)
if test "$HAVE_XF86VIDMODE" = yes ; then
dri_modules="$dri_modules xxf86vm"
fi
Add the package as an optional dependency to have reproducable builds.

DRI3 support is optional in mesa3d, but mesa3d expects it by default,
so add configure options to disable it when necessary and add the
needed dependencies for DRI3 support. Fixes:
===============================
checking for DRI3PROTO... no
configure: error: Package requirements (dri3proto >= 1.0) were not met:
checking for PRESENTPROTO... no
configure: error: Package requirements (presentproto >= 1.0) were not met:
configure: error: Package requirements (x11 xext xdamage xfixes x11-xcb xcb-glx >= 1.8.1
xcb-dri2 >= 1.8 xcb-dri3 xcb-present xcb-sync xshmfence >= 1.1) were not met:
Package xshmfence was not found in the pkg-config search path.
===============================
This defconfig was broken and fixed by this patch:
BR2_TOOLCHAIN_EXTERNAL=y
BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_EUDEV=y
BR2_PACKAGE_MESA3D=y

Currently, we only pass --enable-opengl is at least one DRI driver is
enabled, since full OpenGL is only possible with a DRI driver (and the
X.Org stack). Otherwise, we pass --disable-opengl on the assumption that
OpenGL is not possible.
But mesa3d's ./configure is a bit weird: enabling OpenGL-ES and diabling
full OpenGL is an error (see autobuild failure below).
It turns out that, if there is no DRI driver enabled, but --enable-opengl
is passed, ./configure will behave properly wrt OpenGL-ES, and will not
build the full OpenGL libgl.
Thanks to Paul for explaining this.

Full OpenGL is only provided when:
- a DRI driver is enabled,
- and X.Org is enabled
Since DRI driver depend on X.Org being selected, this means that we
can (have to) enable full OpenGL as soon as a DRI driver is enabled.
On the other hand, Gallium drivers, which currently do enable full
OpenGL, only really provide OpenGL EGL and GLES, not full OpenGL.
So we exclude Gallium drivers when checking whether to enable full
OpenGL in mesa3d.

Currently, full-OpenGL is enabled by checking that at least one driver
is enabled. This is done by checking that the just-constructed lists of
drivers are not empty.
But we already have a variable that is set to 'y' as soon as a driver
is selected:
- DRI drivers select BR2_PACKAGE_MESA3D_DRI_DRIVER
- Gallium drivers select BR2_PACKAGE_MESA3D_GALLIUM_DRIVER
- both BR2_PACKAGE_MESA3D_DRI_DRIVER and BR2_PACKAGE_MESA3D_GALLIUM_DRIVER
select BR2_PACKAGE_MESA3D_DRIVER
So, BR2_PACKAGE_MESA3D_DRIVER is set to 'y' as soon as at least one
driver is selected. We can use that variable rather than comparing the
lists of drivers.
Also, rearrange the code in a more logical way, by moving the code that
enables OpenGL nearer to the code enabling EGL and GLES.

Mesa3D only installs khrplatform.h if EGL support is enabled, whereas
this header file is needed by the headers of OpenGL|ES and OpenVG.
The supplied patch forces Mesa3D to install this header unconditionally.

- add options to select mesa3d drivers
- uClibc support was fixed in mesa3d v9.2
https://bugs.freedesktop.org/show_bug.cgi?id=51782
therefore mesa3d-uclibc-locale.patch was removed
- removed MESA3D_AUTORECONF=yes as it was needed only
for mesa3d-uclibc-locale.patch
