Makefile: fix forced rebuild of LLVM

Browse Source 
This is a small change that makes sure not to force a rebuild of LLVM
every time.

For example, I might run:

    make llvm-source
    make llvm-build ASSERT=1

And then I might make some temporary changes to LLVM to test out a patch
for example. So I run:

    make llvm-build

...and my whole build cache gets destroyed.

This commit addresses this issue by not forcing a re-run of CMake with
every `make llvm-build` invocation.
