MODSIGN: Change from CMS to PKCS#7 signing if the openssl is too old
The sign-file.c program actually uses CMS rather than PKCS#7 to sign a file
since that allows the target X.509 certificate to be specified by
subjectKeyId rather than by issuer + serialNumber.
However, older versions of the OpenSSL crypto library (such as may be found
in CentOS 5.11) don't support CMS. Assume everything prior to
OpenSSL-1.0.0 doesn't support CMS and switch to using PKCS#7 in that case.
Further, the pre-1.0.0 OpenSSL only supports PKCS#7 signing with SHA1, so
give an error from the sign-file script if the caller requests anything
other than SHA1.
The compiler gives the following error with an OpenSSL crypto library
that's too old:
HOSTCC scripts/sign-file
scripts/sign-file.c:23:25: fatal error: openssl/cms.h: No such file or directory
#include <openssl/cms.h>
