Changing the build system used by projects is hard, and changing some
build systems is not possible.

Would you be ok with a -fcompilation-db option that makes clang record
the necessary information to that db? By the way, any ideas how to
handle files that are compiled more than once? For example, when cross
compiling every file in lib/Support is compiled for the build and host
targets.
