 Turns out nope, it was '''not''' a `ccache` issue; I tried doing it
 manually and ran into the same issues. Here it is with the `-v` flag that
 it recommended trying:

 As you can see it is still using `/usr/bin/as`, which is the same
 assembler that gcc would have been using. Passing the `-integrated-as`
 flag to `clang` allows the file to compile successfully:
