Just to clarify this point: while this is an accurate description of
the distinction, the Linux kernel and most bootloaders intended for
use with it, including U-Boot, have arranged for compatibility with
Linux-targeted compilers to simplify people's lives.

It doesn't always work, especially for the latest tools and older
versions of U-Boot, because the arrangements are a bit fiddly.
