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.
