When building with clang and there is no gcc available, running merge_config.sh fails without this fix because it can't build scripts/basic/fixdep with HOSTCC hard-coded to be gcc in the top-level Makefile. This was discovered while trying to build big-endian arm64 kernels with clang for kernelci.org in a Docker container with only clang as a host compiler. While this fix seems like a very obvious thing to do, it's equally surprising that it hasn't been done before. This is why I'm sending this as an RFC; there may be a very good reason why the compiler variables still need to be hard-coded with gcc in the top-level Makefile.
