This new version brings in support for egl-wayland, the EGL extensions
aimed at making it possible to implement Wayland servers and clients. As
such, nvidia-driver becomes the second EGL implementation in Buildroot
that can act as a libegl provider with egl-wayland extensions.
In this version, it becomes possible to use our kernel-module infra,
with just a little few minor tricks: we need just specify the Linux
source and build trees (they are the same for us) and the list of
modules to build. We still need a little patch against the Kbuild files.
We also get rid of the LIBS_NO_VERSION trick and always use complete
filenames, as more libs are now packaged with different version in their
filenames, and even some with no version at all.
When installing libs, we switch from a shell loop to a make foreach
loop, which is easier to handle. It has the side-effect (and advantage)
of displaying the install commands for each library, rather than a
single biggish one, so it is easier to see what goes wrong. This also
means that an error in each phase of the install (the copy of the files
then each symlink) can be caught more easily (it was not previously):
each sequence is now its own make command; we need not use "|| exit 1"
after each command, even in a if block, because the if blocks returns
with the exit code of the last command in it; e.g. if an ln fails, the
if-block in which it is enclosed will return the exit code of ln, and
make will catch it.
Similarly for the X driver modules and each of the programs installed:
we now can catch any failure in the isntall of those.
All of this somewhat simplifies the .mk. It is a little bit longer, but
the structure is saner and more explicit.

This patch only adds the userland part. Unless other such other
packages (which we named like: rpi-userland), we do not replicate this
naming scheme with this package, as a future patch will also enable
building the kernel part of the driver. So, it is better to just name
that package with -driver, rather than with -userland and renaming it
afterwards.
[Thomas:
- Rewrap Config.in help text.
- Add a comment to explain why mesa3d-headers, xlib_libX11 and
xlib_libXext are part of the dependencies.
- Fix typo in comment about library installation: s/The/Then/
- Use 'addsuffix' instead of 'patsubst' to calculate the final
filename of libraries to install.
- Use more temporary variables to make the library installation loop
clearer: 'libpath' is the relative path of the library in
nvidia-driver sources, 'libname' the base name of the library,
'libsoname' the soname of the library, and 'baseso' the base .so
symlink name.]
