kconfig: Add LSMOD=file to override the lsmod for localmodconfig
Doing the following: make LSMOD=file localmodconfig Will make the streamline-config code use the given file instead of lsmod. If the file is an executable, it will execute it, otherwise it will read it as text. make LSMOD=/my/local/path/lsmod localmodconfig The above will execute the lsmod in /my/local/path instead of the lsmods that may be located elsewhere. make LSMOD=embedded_board_lsmod localmodconfig The above will read the "embedded_board_lsmod" as a text file. This is useful if you are doing a cross compile and need to run the config against modules that exist on an embedded device. Note, if the LSMOD= file does is not a path, it will add the path to the object directory. That is, the above example will look for "embedded_board_lsmod" in the directory that the binary will be built in (the O=dir directory).
