FYI, this seems to break in 2024.02.6. The
TOOLCHAIN_EKTERNAL_BOOTLIN_*_STABLE refer to
BR2_TOOLCHAIN_HEADERS_AT_LEAST_4_19.

However, the website https://toolchains.bootlin.com/ suggests the
stable headers are 5.4.296. Perhaps those toolchains only need updating?

It isn't immediately clear which headers are in ARM 14.2.rel1, but that
claims to be AT_LEAST_4_20

The end result I'm seeing is systemd-networkd doesn't compile.
Compilation failed in 2025.02.5, actually, due to the same macro.

Does this need an upstream patch?
