If I comment out code from 7ca1c9dcb7b0 as follows, sign-file.c will build. The
kernel will then build and run. I'm doing dev/test builds with no need to sign
anything. MODULE_SIG_ALL is not set.

Pardon my ignorance of the signing details, but I don't see an indication
of having selected PKCS#7 with SHA1 in my .config. What am I looking for?
