Reasonably often people will want to build the loader w/o any drivers.
Be that debugging an issue in the former, distribution bundle or other.
Currently there is an artificial restriction preventing people to build
a config like the following:
meson build/ -Dglx=dri -Ddri-drivers= -Dvulkan-drivers= -Dgallium-drivers=

This is a WIP, since it's obviously incomplete/wrong. Input or fix
would be appreciated.
Thanks
Emil

I'll have to think about this some more, I'm still not exactly sure why you'd
want to build the loader without a driver (although I could see why you might
want the driver without the loader).
Building both separate breaks away the dependency for llvm/clang while
building the loader package (mesa), thus eliminating the bottleneck, the
long build time of llvm/clang, in a complete build cycle of a whole
distribution rebuild for the packages "waiting" on mesa to complete. The
mesa-drivers package can wait for llvm/clang in the meantime. Right now
i have solved this by building the classic swrast with mesa and
instantly throwing it away after the build is finished.
Btw: Building the drivers without a windowing system would be nice as
well, this applies to the above use case where the -drivers package does
not need a windowing system, as it is contained in the other package.

Usually both should work - loader w/o driver and driver w/o loader.
Imagine you're debugging some issues in libEGL - you don't want to
build driver X/Y/Z.
Additionally, distributions build latest loader and use it with DRI1
era drivers.
Ah, okay, building a new loader to test with dri1 drivers is a reasonable use
for this.
Having them build a driver, without an obvious reason is quite strange.
