Hello,
I have encountered an issue with the following setup:
* host toolchain gcc 7.5.0 (Ubuntu 18.04 LTS)
* target toolchain gcc 9.4.1
In this case I got build error while compiling DTBs because of the following flag: -fmacro-prefix-map
This flag was known to my target toolchain (CC) but not by my HOSTCC.
One might say that Ubuntu 18.04 is pretty old and I should upgrade but I think it's fundamentally broken to check flags on toolchain A and use them on toolchain B. We could have other issues like this in the future.
I'm proposing this change to open the discussion.

Use target CPP to pre-process dts as supported flag checks are done on
target toolchain
