MarsSeed [1] filed a deletion request for usbboot [2]: Broken, unused VCS package from 2021.
Also, despite the bogus arch=('any'), this PKGBUILD actually compiles
C source into machine code, and the runtime is intended to be executed
only on ARM / Aarch64 devices like the Raspberry Pi.
Therefore this is not compatible with Arch Linux (x86_64).
