Building tools separately is necessary for the existing cross-complation usecase. We generalize this by introducing two cmake vars that enable exporting and importing prebuilt tools. The intended usecase is to enable ASAN-built filament without having to run ASAN-built matc (which is prohibitively slow). build.sh has been modified to add a `-y` flag forprebuilding tools.
