[0/1] kbuild: Support building a tree of modules with -M=<root>

Message

Currently when building lustre against 5.3 kernel modules fail to
generate <module>.ko files.

Lustre builds a tree of modules however the numerous modules.order files
are created but only the modules.order file at the root appears to be 
read.

This changes the the scheme for KBUILD_EXTMOD to write to and read from
a single modules.order file at the root.
