Previously, we included the stubs in our driver binaries, so they didn't
call the actual system libraries for these functions. This was enough to
build-test the Android code in CI without even the NDK.
To make NDK-built Mesa drivers useful, we need to link against these
system libraries that aren't present in the NDK. Split the symbols to
separate non-installed shared libraries and link against those, so that
when you drop the resulting .so in your /vendor/lib64/hw/, it just works
out.
