Subject: [PATCH] Makefile.inc: Adapt $(spc) definition

GNU Make 4.3 is more picky about the $(spc) definition. It seems, the
variable ends up empty. The old definition worked for nearly 8 years,
RIP.

Tested with GNU Make 4.2.1 and 4.3.

Subject: [PATCH] Makefile.inc: Use `define` for cbfs-files-processor-defconfig

The body contains a `#` and GNU make 4.3 disagrees with earlier versions
if it should be treated as a comment. Turn it into a `define` which has
clearer semantics regarding comments (interpretation is supposed to be
deferred until the variable is expanded).
