[PATCH] kbuild: normalize paths in quiet compile output

[Yang Wang]

Composite objects may contain relative components in their member object
paths. This can make quiet compile output include noisy dot-dot components,
for example:

  CC [M]  drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_module.o

Use the existing normalize_path helper for quiet C and assembly compile
output so the same target is printed as:

  CC [M]  drivers/gpu/drm/amd/amdkfd/kfd_module.o

The actual compile commands still use $@, so object paths, dependency
tracking and generated files are unchanged.
