I'm trying to debug u-boot build failure. I've found single command that fails:

The question is what In file included from <built-in>:1: does mean? How can I understand exact include path from tools/envcrc.c which I'm trying to compile to include/compiler.h? tools/envcrc.c didn't include compiler.h directly: https://github.com/u-boot/u-boot/blob/v2022.07/tools/envcrc.c.
If you look at the command line, there is the option -include ./include/compiler.h, which tells the compiler to include that file even though there is no such #include directive in any source file. The error message would normally state the source file from which include/compiler.h was included, but here there is no such file, so they put <built-in> in the message instead.
The actual issue is that include/compiler.h seems to be using a macro CONFIG_IS_ENABLED which was never defined. You should try to investigate why that is, or how or where it was supposed to be defined.
