No one has needed to before because currently-supported compilers all
have options to specify the output file name.

We support adding `src.c` and `src.cxx` together. The object file
names need to be distinct.

Possible approaches to deal with this include:
* Extend the Ninja generator with settings to tell it about the above
names.
* Set `CMAKE_<LANG>_COMPILE_OBJECT` to contain a follow-up command
after compiling to rename the compiler-produced depfile and move
it to where Ninja wants to see it.
Either way there could be problems with source files with the same base
name compiling at the same time and overwriting each other's depfiles.
Ideally the compilers should be fixed instead.
