[ale] Libgcrypt warning: MD5 used - FIPS mode inactivated

ls -ltR /etc/pki/ reveals no newly created files prior to enabling FIPS.

There are a few package differences, but for things like openmanage and
some additional tools needed on the production side.   libgcrypt and
freetds (contains tsql) are identical.

Last night I removed/reinstalled freetds with no success (the old conf file
was moved out of the way).
