I'm not sure that adding this is the right thing to do. Based on the comment
below it says "This function must be cryptographically secure" but now the
caller can't be sure that is the case.

Please ignore changes in base folder. It is a temporary workaround for a crash
in nacl_secure_random(), because I would like to use trybots for all platforms.
And the nacl_secure_random() will be fixed soon. I will remove this changes
before landing.
