I have a very specific question about the Waf build system. I apologize if
I missed this information somewhere in the documentation.

 From looking at ./waf --help it doesn't look like Waf would have a
ccache-like functionality built in.

When using CMake build system, I am used to providing

-DCMAKE_CXX_COMPILER_LAUNCHER=ccache

that makes CMake switch to using ccache. Is there an equivalent option for
Waf or is there a native way in Waf for caching object artifacts?

you may have a look at this:

https://gitlab.com/ita1024/waf/blob/master/waflib/extras/wafcache.py

I don't know if this works with RTEMS. Do you want to use this for the RTEMS build? I am not sure if it is worth the trouble since RTEMS builds in a couple of seconds.
