Revert "kbuild: make all file references relative to source root"
This reverts commit cacd22ce69585a91c386243cd662ada962431e63.
-ffile-prefix-map breaks 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.
Revert the unconditional usage of -ffile-prefix-map.
