kbuild: prevent modpost from looking for a .cmd file for a static library linked into a module
This fixes a compile time warning which occurs whenever a static library
is linked into a kernel module. MODPOST tries to look for a
".<modulename>.cmd" file to look for its dependencies, but that file
doesn't exist or get generated for static libraries.
This patch prevents modpost from looking for a .cmd file when a module is
linked with a static library
