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).
