    kbuild: cmd_dtc_cpp: extract deps from both gcc -E and dtc · 85f02be8

    Prior to this change, when compiling *.dts to *.dtb, the dependency
    output from dtc would be used, and when compiling *.dtsp to *.dtb, the
    dependency output from gcc -E alone would be used, despite dtc also
    being invoked (on a temporary file that was guaranteed to have no
    dependencies).
    
    With this change, when compiling *.dtsp to *.dtb, the dependency files
    from both gcc -E and dtc are used. This will allow cmd_dtc_cpp to
    replace cmd_dtc in a future change. In turn, that will allow the C pre-
    processor to be run transparently on *.dts, without the need to a
    separate rule or file extension to trigger it.
