To improve speed of building, you may consider the argument DLLVM_BUILD_TESTS (I have OFF for this argument), DLLVM_TARGETS_TO_BUILD (x86 maybe), DLLVM_ENABLE_PROJECTS - select only projects that you need.
Hope that help!

Using ccache will normally not result in any performance improvements
for a one-off build and typically even decrease performance. Whether it
helps for update builds is questionable too.
