[random] Merging to master for 1.75 release

Is there any possibility of merging 'develop' to 'master' for the random 
library for the 1.75 release ? The 'master' branch has not been updated 
for 2 years, or since the 1.70 release. While I am not claiming all 
invaluable fixes I know my fix for Embarcadero C++ clang-based support 
and another fix for correctly auto-linking random_device is among the 
'develop' branch fixes which have never made it to the 'master' branch.
