kbuild: do not redirect the first prerequisite for filechk
Currently, filechk unconditionally opens the first prerequisite and redirects it as the stdin of a filechk_* rule. Hence, every target using $(call filechk,...) must list something as the first prerequisite even if it is unneeded. '< $<' is actually unneeded in most cases. Each rule can explicitly adds it if necessary. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
