This fixes:
$ uname -m
armv8l
$ env CHECK=./sparse ./cgcc -no-compile memops.c
/usr/include/arm-linux-gnueabihf/gnu/stubs.h:7:12: error: unable to open 'gnu/stubs-soft.h'

Hello,
I added
env CHECK=./sparse ./cgcc -no-compile memops.c
to the package building process and that failed on armhf (i.e. Armv7
CPU with Thumb-2 and VFP3D16 or better) with the above error.
With that applied all Debian primary architectures work fine; see
https://buildd.debian.org/status/package.php?p=sparse&suite=unstable
Best regards
Uwe
