we absolutely should do this. I believe we have some communication
problems, because I brought this up multiple times.
I am not sure how to solve it, I can think of multiple ways. But it
would help if you just apply this path as it is, and let it build for
the ~10 architectures. Can you do this somehow, maybe just keep it in
First, it helps if we know we start with a working build (on all
platforms) before modifying it, and which libraries would normally be
Then I would like to be able to make a list of libraries for all
architectures, since I believe this will differ alot.
Also (I brought this up before): I dont know if the shared sanitizer
libraries are actually used anywhere. The static libraries dont make
problems, so if we can drop the shared ones then this is one problem
