When you run "make C=2 arch/.../crypto/" then sparse shall be run
for all .c files also if they are already built.
But due to the re-implementation of some parts of the kbuild logic
in the makefile this does not happen with the -glue file.

A minor detail - but this may not be the only wreckage we see over time.
