Thanks!

I'm a little uncertain about changing Bin, SingleBin, and Example. My thinking is that if you have a flag that is required to link a bin, then the flag would also likely be required to link a unittest of the bin (since they are mostly the same thing). Can you say more about why those are being changed?

I initially assumed they were different based on intuition.

I recalled a case where a binary was compiled for a bare-metal target, and I used custom test frameworks to run tests in the same environment. If the current behavior changes, similar use cases could break.

So, I reverted to the previous behavior for Bin, SingleBin and Example.
