2964b8a6f6 fix #874 
coverity reported a warning regarding a memcpy() overwrite.
This is a false positive (the memory area is large enough),
but it's true that it's not trivial to determine (encompassing struct),
and it's proper anyway to only memcpy() just the right amount of data.

073fe18edf [ossfuzz] Fix parallel builds 
With `make -j` multiple builds of `standaloneengine.o` happened in
parallel. Fix this by detecting `standaloneengine.o` and moving it to a
depedency.
