According to Documentation/Changes, make 3.80 is still being supported
for building the kernel, hence make files must not make (unconditional)
use of features introduced only in newer versions. Commit 1bf49dd4
("./Makefile: export initial ramdisk compression config option")
however introduced "else ifeq" constructs which make 3.80 doesn't
understand. Replace the logic there with more conventional (in the
kernel build infrastructure) list constructs (except that the list here
is intentionally limited to exactly one element).
