Commit8370edea81("bin2c: move bin2c in scripts/basic") moved bin2c to the scripts/basic/ directory, incorrectly stating "Kexec wants to use bin2c and it wants to use it really early in the build process. See arch/x86/purgatory/ code in later patches." Commitbdab125c93("Revert "kexec/purgatory: Add clean-up for purgatory directory"") and commitd6605b6bbe("x86/build: Remove unnecessary preparation for purgatory") removed the redundant purgatory build magic entirely. That means that the move of bin2c was unnecessary in the first place. fixdep is the only host program that deserves to sit in the scripts/basic/ directory.
