Fix precompiled headers building with clang

Browse source 
Since 24.05 (I think) we need to pass `-c` or Clang thinks we want to
compile *both* a final executable and precompiled header file, and
complains that we cannot use `-o` with multiple outputs. `-c` seems fine
with GCC too, so I just put it in there conditionally.
