Subject: [PATCH 0/2] kbuild: revert relative paths in compiler outputs

-ffile-prefix-map/--remap-path-prefix break the ability of debuggers to
find the source file corresponding to object files. As there is no
simple or uniform way to specify the source directory explicitly, this
breaks developers workflows.
