We obviously need to fix this before we can upgrade to a new OpenSSL version.

Do we really have a need for the random functions? These seem the only
ones that use floating point, which the UEFI spec does not permit, so
it would be better if we could fix this by removing the dependency on
FP in the first place (and get rid of ArmSoftFloatLib entirely)
