It's not just ARM32, I saw it on ARM64 as well and I'm pretty
sure it appears on any bare metal "none" compiler.

kernel.org host "nolibc" cross compilers (Arnd makes these):
https://mirrors.edge.kernel.org/pub/tools/crosstool/
and those WORK, because they use the kernel minimal
libc which defines __linux__.

So a "nolibc" compiler works but not "none" compilers.

I think the test robots all use Arnds nolibc compilers or the
compilers from distributions so they don't see this.

A typical example of breaking compilers: ARMs supported
"none" compilers:
https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads

Linus Walleij
