From: André Draszik <adras...@tycoint.com>
Requiring all build systems for external kernel modules to
place Module.symvers directly into ${B}/. is quite an
artificial assumption/requirement. It doesn't have to end
up there, but could easily end up somewhere below ${B}.
Allow to override the location below ${B}
Note that we still don't make use of multiple
Module.symvers in case there are any generated by one
single kernel module build, but this is no change in
behaviour from before and could be added if there really
is a demand for that.
