[Skiboot] [PATCH] external/opal-prd: Make compilation prerequisites as order-only prerequisites

Makefile creates symbolic link to libflash, ccan, etc. Presently we added them
as normal prerequisites. In some cases (like we compile skiboot after compiling
opal-prd) it will result in recompiling source again during make install. Hence
make it as order-only prerequisites.
