Subject: [PATCH] deps: Make more sources conditional

Fetching all the dependent sources - including at least one copy of LLVM
- can take a surprising amount of time. Mesa needs to build ANGLE as
part of CI, and the cost of downloading all the sources all of the time
is not OK for the number of dependencies we don't need during the build.
