That will depend on how glibc is implemented. Simplest might be to use 
compile-time interposition, which is common in Gnulib. E.g., Gnulib 
would supply its own getentropy.h which does "#define getentropy 
rpl_getentropy", so that Gnulib-using applications always call 
rpl_getentropy from the linker's point of view. This sort of thing is OK 
for Gnulib, as it's not intended to be a separate library.
