Similarly seen for GCN target, and this is now fatal after Florian's recent
changes (I presume -- and I fully do support those, for avoidance of doubt):

GCC's suggestion to "include ‘<stdlib.h>’" needs to be carefully reviewed, in
case this is meant to be buildable in an environment without C library headers?
