[PATCH] kbuild: use 'else ifeq' for checksrc to improve readability

[Masahiro Yamada]

'ifeq ... else ifeq ... endif' notation is supported by GNU Make 3.81
or later, which is the requirement for building the kernel since
commit 37d69ee30808 ("docs: bump minimal GNU Make version to 3.81").

Use it to improve the readability.
