Kernel Makefile Change for multiple machines and modules

Compiling a single kernel for a number of wildly different machines
on a single host is simple enough in Linux as long as one does not
play with modules.

As soon as modules muddle the issue, one encounters a problem of
installing them, as compiled, on a single machine, becomes annoying:
one must manually jiggle the /lib/modules/something hierarchy.

Therefore, as a quick, slap-together, solution, enclosed is a Makefile
patch to add another target to the Makefile - modules_altinstall - which

stuffs new modules into /lib/modules/x.y.z.ALT.
