[PATCH][RFC] Makefile: Add modules-collect target

[Bodo Eggert <7eggert@gmx.de>]

I frequently (but not frequently enough) compile kernels on one machine 
that are to be used on another machine. If It needs modules, I will need a 
way to collect all modules that need to be transfered into a directory.
Usurally I'll want INSTALL_MOD_PATH=somedir make modules_install, but I
keep forgetting the name of the variable. I suppose I'm not the only one.

Therefore I suggest a modules_collect target, which will collect all 
modules into a single directory ready for being tared and transfered:
