kbuild: remove the first line of *.mod files
The current format of *.mod is like this: line 1: directory path to the .ko file line 2: a list of objects linked into this module line 3: unresolved symbols (only when CONFIG_TRIM_UNUSED_KSYMS=y) Now that *.mod and *.ko are created in the same directory, the line 1 provides no valuable information. It can be derived by replacing the extension .mod with .ko. In fact, nobody uses the first line any more. Cut down the first line. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
