The fixdep binary is being compiled and linked in one step. While the host linker flags are passed to the compiler the host compiler flags are missed. That leads to build errors at least on x86_64, arm64 and s390 as result of the compiler vs linker flags inconsistency. For example, during RPM package build redhat-hardened-ld script is provided to gcc, while redhat-hardened-cc1 script is missed. Provide both KBUILD_HOSTCFLAGS and KBUILD_HOSTLDFLAGS to avoid that.
